Free Chemical Drawing Programs
Should you decide to work up your laboratory report on your computer, there are several chemical graphics programs you might find useful. In no particular order they are as follows:
Symyx Draw formerly Isis Draw found at http://symyx-draw.en.softonic.com/
KnowItAll Academic Edition found at http://www.knowitall.com/academic/
Both programs require you to register but registration is free. These programs can be used for a variety of graphics. KnowItAll also has a very nice clipart section of laboratory glassware.
During the semester you will be given four (4) exams during the class period and a Final Exam. There will also be homework assignments associated with each chapter covered. The completed homework sets are due before the exam covering those chapters. The homework assignments will be completed on OWL and your grade will be posted on eCampus. The exam dates listed on the schedule are tentative. Any changes in an exam date will be announced at least one (1) week prior to the exam and this information will be posted on eCampus. All exams are cumulative although the material covered since the last exam will be most heavily emphasized. The Final is cumulative, should you miss the final a grade of zero (0) will be awarded. The scheduled exams and Final will be in a "fill in the page" format. Chemistry 2423 covers chapters 1-11, 17 and Chapter 18. This is the first semester of a two-semester course, skipping material is not an option. Completion of both the lecture and the lab is required to receive a single grade for 4 credit hours of work.
Lecture this semester is in "double format". Because of the time required for organic experiments and scheduling constraints, we will meet in the lecture room S209 on Monday, Jan. 14 for a double lecture, the next class will be in the lab room S226 (Wed. Jan. 16). The next class meeting will be in the lecture room, etc. Because of the holiday on Monday Jan. 21, our third class period will be in S209. Barring any days lost due to weather or other school outages, we will continue on with having lecture in S209 on each Wednesday and lab in S226 each Monday. While we may either have a lecture or perform a laboratory experiment when in S226, in general the meetings in S226 will involve a lab so you will need to come prepared to perform an experiment each Monday. In consideration of the material and the length of the period, there might be a brief break in the middle of the class lectures lasting approximately 10 minutes. Should a break be provided, please be considerate and return promptly from your break.
Exams. The scheduled major exams will typically have between 5 and 10 sections. Typically the exams will have sections dedicated to reactions, nomenclature, and theory. As we reach mechanisms, stereochemistry, synthesis, and spectroscopy, these will also be included as sections in the exams. Practicing these by completing the homework assignments will improve your exam performance. I will return the exam once all students have taken the exam and it is graded. (See make-up exam policy below.) The four major exams are worth 40% of your final grade.
The Final Exam will be given on Friday, May 3 at 7:45 am. You have until the end of the semester to make certain that you have this day and time free. The Final Exam is comprehensive and is worth 20% of your final grade. The Final Exam will follow the same general format as the regularly scheduled exams.
Homework. Homework comes in two forms. First an online web-based learning system, OWL, which is computer based. The second is a mechanism homework handout that will be available on eCampus.
OWL. There are OWL chapter assignments for all 13 chapters that will be covered; I will lecture over Chapters 3-11 and 17-18. There are review questions listed for Chapters 1&2. OWL is an interactive system, to receive full credit you will have to "demonstrate mastery" of a particular question set. There is no limit to your attempts. The questions are based upon those at the end of each chapter. The majority of the questions chosen for these assignments are algorithmic. This means that the values and compounds change for the question. You do not get the same question again for a great many submissions and, even then, the actual values used may be changed. (While answering additional questions in that section may be good practice, you will not get credit for repeating the section or answering additional questions in a mastered section.) Plan to spend a significant amount of time on OWL (1 to 2 hours per night). OWL keeps track of your progress so you can work on the homework throughout the time (weeks) the assignment is active. Again, you cannot wait until the last minute to complete your OWL homework; you will run out of time. OWL records each visit you make to the program, so I will be able to monitor your usage of the system. Your points accumulated on your OWL assignments will be posted and kept updated on eCampus. You may choose to work on your homework as often as you wish/need (you will not have to re-answer previously completed sections). The homework must be submitted by the deadline listed above in order to receive credit. Your score for the homework component of your grade will be the average of each of the chapter assignments. Skipping a chapter will result in a grade of zero for that chapter. Failure to do the required OWL homework will cost you 10% of your grade in the course.
All of the computer labs at Blinn are available and should run OWL well. If you encounter any problem with any of the Computer Lab computers, let me know immediately so the lack of compatibility can be corrected. Waiting until the last few days of the assignment to begin working on your homework and finding you have computer problems is not an excuse and no additional time will be granted for these situations.
Homework will be graded on the following criteria: completion by deadline; the completion of the assignment, and the percentage of answers that are correct.
The OWL homework is worth 100 points or 10% of your grade in this course. If you fail to submit your homework, you will receive a grade of zero for that section. I need to know as soon as possible if you are having difficulty accessing OWL. Each chapter is worth 10 points. You will receive a score for each Chapter Assignment. Your homework grade will be the total of these thirteen (13) assignments (a possible 30 point bonus if you get full credit on all 13 assigned chapters). Your score on each section will be posted on eCampus. This way you can assess your current “grade” in the course throughout the semester.
I am available during office hours to assist you. I am happy to help you with any of OWL that you are having problems with. This does not mean that I will do all of your OWL homework for you. If you are having a problem with a few questions, I can assist, but I will not work all of the problems with you.
Once again, each OWL section is open for several weeks. Waiting until the week (or days) before an exam and suddenly having computer or network problems is not an acceptable excuse for not being able to complete your homework assignment. The OWL assignments follow the chapters in your text book. In the past there has been a very high correlation between exam grades and the completion of assigned homework. Therefore, the deadline for completing each group of chapters will be 8:00 pm the night prior to that particular exam. The table below is the list of current deadlines. Should an exam be moved, the deadlines would be adjusted accordingly. The OWL "clock" is the official time used. Once the deadline has passed, you will receive no credit for additional homework completed.
Mechanism Homework. You will be given a homework set dealing with organic reaction mechanisms. It is worth 50 points. This will require you to suggest reasonable mechanisms for chemical transformations shown. You will need to use curved arrows to indicate the motion of electron pairs (or single electrons for radical reactions). This set will consist of between 5 and 10 reactions. If a specific stereochemistry is shown in the product, your mechanism must clearly show how this particular stereochemistry resulted from the movement of electrons you show. Grades are based upon completion and correctness. You will receive a 10 point reduction for each day that they are late (3 day’s late results in a grade of zero). These are worth 50 pts or 5% of your final grade.
Because of space, time, and equipment considerations, you may work with one partner for the laboratory. You must be properly attired (closed-toe shoes, sleeves, coverage from neck to below knees) and have appropriate eye protection to be allowed to perform an experiment. You will be dismissed from the laboratory for violating the safety rules (wearing inappropriate clothing, no safety goggles (or lack of proper use), wearing sandals or flip-flops, etc.). Any visible food or drink container (even if it is sealed) is a safety violation in lab and will cause your immediate removal from the laboratory with a grade of zero being assigned for that experiment.
Dismissal from the laboratory will not count as an “official” absence but it will result is loss of all points associated with that experiment.
You will be performing 10 experiments this semester. If you miss a lab for any reason (illness, or dismissal for no eye protection or no shoes, etc.), a grade of zero will be awarded for the Laboratory Grade. Absence from the laboratory on the day of the experiment for any reason (excused or unexcused) will result in you receiving a zero for all parts of that experiment.
The laboratory component will make up 25% of your final grade. It is based upon your active participation in the laboratory activity. You should be prepared to run a laboratory experiment every day we meet in S226. You must have your lab manual, appropriate clothing, foot wear and chemical resistant safety goggles for each lab session. Be aware that some days, I may choose to continue the lecture or to spend the laboratory time covering a problem set. Regardless, you must attend each lab prepared to do a lab. A few of the experiments may be "dry labs" in which concepts and not experimental procedures are emphasized and the safety requirements are ‘relaxed’ for that session. Laboratory experiments and the reports for the experiments will be graded and will count towards a maximum of 250 pts or 25% of your final grade.
The laboratory schedule is outline below. The laboratory component of OCHEM 2423 begins with experiments employing the various separation and identification techniques that are associated with the organic laboratory. Once you have used these techniques, you will later use these techniques in several “synthetic” experiments in which you will run several chemical transformations that are typical of classical organic transformations. These two types of experimental types will require different approaches to their laboratory write-up.
‘Techniques’ PreLab Write-up (10 pts)
Before coming to the laboratory, you should read both the experimental procedure and read the technique sections suggested for that experiment. You should then write the general experimental procedure is sufficient detail into your laboratory notebook (duplicating page notebook) so that you can use this rather than your lab manual to proceed through the experiment. You may paraphrase what is written in the laboratory manual and only list the individual steps required in your procedure. Since the first series of experiments concentrate on the various techniques associated with isolation and analysis of your reaction products, the first several experiments will be more of an outline of the procedure or a flow chart of the steps you will follow and what happens (chemically) at each step where appropriate. A copy of this procedure should be turned in at the beginning of each experiment. If you wish to do this on the computer, a printout of this will also be accepted. It would be prudent to sketch the equipment or the experimental set-up that is associated with the experiment (until you are familiar with graphics software it is usually faster to sketch this by hand). Regardless of whether you choose to use the laboratory notebook (duplicating page format) or decide to do your pre-lab on the computer, you will need to have a duplicate copy to work from after you turn in the written prelab write-up.
Outline the various steps involved, volumes of solvent or material involved and a short statement of what you will be doing. You should be sufficiently detailed so that you can follow this write-up rather than the laboratory manual itself. You will need to turn in a copy of this to me at the beginning of the laboratory period (or a print-out with drawing if generated on the computer…the drawing can be hand rendered).
You should list any hazards that might be associated with each experiment in the prelab write-up.
‘Synthesis’ Pre-Laboratory Write-up
Before coming to the laboratory, you should read both the experimental procedure and refer to the techniques suggested for that experiment to refresh your memory of the manipulations that will be required. A general glassware set-up may be shown in this procedure; you should include a sketch of this in your write up. You should then write the general experimental procedure is sufficient detail into your laboratory notebook (duplicating page notebook) so that you can use this rather than your lab manual to proceed through the experiment. You may paraphrase what is written in the laboratory manual and only list the individual steps required in your experiment.
You should include the chemical equation of the reaction being run. Underneath this representation of the chemical reaction you should include a list of the chemicals involved; mol. wt. of each; mass or volume used; and mmol of each (for reactants). For many experiments, we will use volume and density of a material, this information should be included in the pre-lab write up.
For these experiments you should calculated the theoretical yield of the expected product and also include the specific spectroscopic and or classification tests and expected observations you will be looking for.
Again list the hazards associated both with the chemicals you will be using and the potential hazards that might be encountered with the techniques you will be using in this prelab write-up.
In Lab Observations
Regardless of whether the experiment is ‘teaching a technique’ or demonstrating a classic chemical reaction, any changes that are made in the experimental procedure should be first recorded here. We may change quantities, the specific chemical used for the experiment may change (cyclohexanol to 4-methylcyclohexanol), the time and/or temperature required; the order that steps are done, etc. You should record all of these changes under observations.
As you perform the experiment, write down any and all observations (the solution got hot/cold; a lot of precipitate formed in both layers; there was massive bubbling; you spilled/poured out the solution you needed; etc.). As you gain experience, you will begin to recognize what is and isn’t important and begin to select the observations to record. This record is to jog your memory when writing up the experiment so that you can remember what happened (or went wrong) and figure out what associated reaction, solvent effect, etc. actually took place or perhaps what you should have done. You will use this as you write up your report. Again, these observations are for your benefit.
Outline what you actually did in the experiment. If no changes were made, this may be a restatement of your pre-lab write-up with observations included. For the techniques/isolation experiments a flow chart of what you did; the layers separated; the precipitations; etc. should be drawn. For the reaction/synthesis experiments you should include a chemical equation followed by a table of the starting material; the quantities (mass and mmol) used; theoretical yield; actual yield; and percent yield.
The narrative of this section should begin with the materials that you actually used in the experiment. You must include the actual quantities involved (solvents can be in mL; reagents should be listed both as mass used and mmol). The size of reaction flask/vial or separatory funnel used, type of heating, stirring, etc. should be included. If the experiment was for the isolation of a material or identification of an unknown, the identities of the materials; structure, mol. wt., melting point and/or boiling point and other physical properties of each organic material (including solvents like dichloromethane; in which case you should also include density) should be included. You then should describe what you actually did in detail. Include a sketch of the equipment you used and anything you observed as the experiment progressed.
Typically you will also have a melting point to report; a TLC plate from the experiment (taped to the report), a GC plot, or and FTIR spectrum. You should include a discussion of what this analysis showed, what peaks you were expecting to see (or be absent) and any calculations that might be required. You should finish with a conclusion of what you found/isolated and how you might have improved on this portion of the experiment.
Your grades will be posted immediately after the work is graded. Your graded Pre-Lab Write-up and Lab Reports will be returned to you as a single packet at the time of your exam. Lab reports are returned to you at the time of the Lecture Exam. Be aware, if I do not have a lab report from you before I return these experiments at the Lecture Exam, that grade automatically will becomes a zero. I will not accept a lab once I have returned graded labs to the class as a whole.
There are two ways of earning extra credit. Getting full credit on all homework (up to 30 extra points); and tutorials available in OWL will be counted as extra credit points. The deadline for completing these tutorials for extra credit is dependent upon that chapter's deadline.
You are expected to use the computer to access eCampus (and OWL) for this course. All students at Blinn College have Internet access. Computers are available in the Learning Center and in the Open Computer Labs. If you have an e-mail address, it should be on MyBlinn. I expect you to check eCampus and your e-mail for updates on changes in the class. The syllabus, lecture notes, and homework assignments are available on the course eCampus. You are responsible for all class material and any announcements that appear here. You are expected to visit eCampus the notes and homework assignments on a daily basis. If you are unfamiliar with eCampus, you may access it at https://ecampus.blinn.edu. You logon to eCampus the same way you log onto MyBlinn. You will be able to check on your current standing in the course and your points to date by accessing this course (your section) on eCampus. I need to know immediately if you have difficulty accessing either eCampus or OWL.
As a general rule to pass this course with a C you must average a raw score of at least 50 pts on the exam portion of the course and do all the homework and perform and turn in all prelab write-ups and reports for the experiments as each is due. A lower exam average or failure to do the homework and/or experimental write-ups will result in a grade of D or F. Should you plan to take OCHEM II your exam scores should average in the 60s or higher for you to have any hope of surviving CHEM 2425. If your exam average is below 40 for the first two exams you will probably not pass the course. Exam 3 is just prior to the deadline for Q drop, that exam will be graded and the grade will be posted on eCampus before Apr. 12 so you can wait until this exam to determine if you wish to continue in the course.
Grading and Grading Policy. CHEM 2423 (4 hr credit) is divided into both lecture (3 hr) and laboratory (1 hr) components. For convenience, the course grade is based upon a 1000 point scale. The lecture will count toward 75% of the final grade (750 pts) and the lab will make up 25% of the final course grade (250 pts). Your grades will be posted on eCampus so you will always know your standing in the course.
Exams (4 x 100 pts)
Laboratory Experiments (10 x 25 pts)
The course grade will be based upon four (4) exams (400 pts total), laboratory reports (250 pts), homework (150 pts), and a comprehensive final exam (200 pts). The exams and final are cumulative. I do not curve, 900 pts (90.0%) is a guaranteed A; 800 pts (80.0%) is a B; etc.
Blinn College Policies
Members of the Blinn College community, which includes faculty, staff and students, are expected to act honestly and responsibly in all aspects of campus life. Blinn College holds all members accountable for their actions and words. Therefore, all members should commit themselves to behave in a manner that recognizes personal respect and demonstrates concern for the personal dignity, rights, and freedoms of every member of the College community, including respect for College property and the physical and intellectual property of others.
Civility Notification Statement. If a student is asked to leave the classroom because of uncivil behavior, the student may not return to that class until he or she arranges a conference with the instructor; it is the student’s responsibility to arrange for this conference.
This statement reflects step one in a possible four step process. The Incivility Protocol is detailed in the Blinn College Student Handbook, www.blinn.edu/student%20handbook.pdf.
The College District believes that class attendance is essential for student success; therefore, students are required to promptly and regularly attend all their classes. A record of attendance will be maintained from the first day of classes and/or the first day the student’s name appears on the roster through final examinations. If a student has one week’s worth of unexcused absences during the semester, he or she will be sent an e-mail by the College District requiring the student to contact his or her instructor and schedule a conference immediately to discuss his/her attendance issues. Should the student accumulate two weeks’ worth of unexcused absences, he or she will be administratively withdrawn from class.
There are four forms of excused absences recognized by the institution:
- observance of religious holy days—The student should notify his or her instructor(s) not later than the 15th day of the semester concerning the specific date(s) that the student will be absent for any religious holy day(s);
- representing the College District at an official institutional function;
- high school dual credit students representing the independent school district at an official institutional function; and
- military service.
Other absences may be considered excused at the discretion of the faculty
member with appropriate documentation. A student enrolled in a developmental course is subject to College District-mandated attendance policies. Failure to attend developmental classes shall result in removal from the course as defined by the College District.
It is the student’s responsibility to officially drop a class he or she is no longer attending. To officially drop a class the student must obtain the class withdrawal form from Enrollment Services, complete the class withdrawal form, secure the required signatures, and return the completed form to Enrollment Services. The last day to drop with a Q is according to the Academic Calendar.
Blinn College does not tolerate cheating, plagiarism, or any other act of dishonesty with regard to the course in which you are enrolled. The following text defines the faculty member’s responsibility with regard to the scholastic integrity expectation for this and all courses at Blinn College.
It is the responsibility of faculty members to maintain scholastic integrity at the College District by refusing to tolerate any form of scholastic dishonesty. Adequate control of test materials, strict supervision during testing, and other preventive measures should be utilized, as necessary, to prevent cheating or plagiarism. If there is compelling evidence that a student is involved in cheating or plagiarism, the instructor should assume responsibility and address the infraction. Likewise, any student accused of scholastic dishonesty is entitled to due process as outlined in Blinn College Board Policy FLB (Local). The Scholastic Integrity Policy is located in the Blinn College Student Handbook, www.blinn.edu/student%20handbook.pdf. In a case of scholastic dishonesty, it is critical that written documentation be maintained at each level throughout the process.
Students with Disabilities
Final Grade Appeal
Make-Up Exams and Labs
There is no make-up provided for missed labs or for late homework. Missed OWL deadlines reduce your chance at bonus points. There is no make-up for bonus points.
Make-up exams. If you miss an exam, you may request a make-up exam. This does not mean that your request will be approved. To request a make-up for a missed exam you must follow this procedure:
- Notify me by e-mail (firstname.lastname@example.org) or by eCampus that you have missed the exam.This way there will be an electronic copy of your notification. (A scheduled doctor's appointment is NOT considered an excused absence.)
- You must notify me of your absence and provide this documentation within 2 days of your returning to class.
- IF your excuse is deemed to be valid and you have sufficient documentation, I will fill out the required form (your name, exam number, and instructions) and place a make-up exam for you at the Learning Center (room L258 in the Library Building). I will then e-mail you a reply that it is there and ready for you to take. This also generates an electronic copy of your notification.
- You will have 1 week in which to take this make-up exam after it is placed in the Learning Center. Failure to read your e-mail is not an excuse for not taking the make-up exam during this window.
- Important!! The test will be removed from the learning center seven (7) days after it is placed there for you. If you have not taken the make-up by this time, a grade of zero will be awarded for that exam. There is no second chance to make-up the exam.
The make-up exam will not be the same exam given to the rest of the class.
Classroom and Lab Conduct
Classroom and Laboratory Conduct
When you enter the classroom or laboratory, you are entering a learning environment. As such, disruptions due to inappropriate behavior will not be tolerated. Talking, reading the newspaper, texting, and other activities that disrupt or detract from the classroom or laboratory learning experience will not be allowed. Eating and drinking are not allowed in Blinn classrooms. As previously mentioned, any visible food or drink container (even if it is sealed) is a safety violation in lab and will cause your immediate removal from the laboratory with a grade of zero being assigned for that experiment.
SAFETY IN THE LABORATORY
You must have enclosed chemical resistant safety goggles, not safety glasses for the lab. You must also dress defensively. It is recommended that you pack and carry an emergency “go bag” ready for lab which contains your goggles, appropriate clothing (sweats or scrubs) if needed, and appropriate closed-toe footwear so that should you forget, you will have clothes, shoes, and goggles that may be used that day for lab. Failure to have safety goggles, dress defensively, or wearing flip-flops or sandals will cause you to be removed from the lab for a safety violation. Failure to use your goggles while in the lab will also cause you to be removed from the lab. You are expected to put on goggles (protecting your eyes) the moment you enter the lab and not to remove them until you leave the laboratory. I am well aware that they are cumbersome, hot, and tend to fog up. These are for your protection and you do not have the option to decline to use them. You will receive one warning to put your goggles on. This first warning will be made the moment chemicals are brought into the room for you to use. The second warning given that day will result in your immediate removal from the laboratory and the assignment of a grade of zero (0) for that entire laboratory experiment (prelab, report, and postlab). Sliding the glasses/goggles up to protect your forehead or hairline is the most common method of getting dismissed from the lab. This will be rigidly enforced. A grade of zero received for a safety violation WILL NOT BE DISMISSED.
IMPORTANT!! If you forget your goggles you will not be allowed to perform the experiment. Your options are to
- Borrow a pair from a friend who may be on campus at that time.
- Buy another pair from the bookstore.
- Miss the lab (unexcused absence) and lose the points associated with that experiment.
You must wear enclosed footwear to the laboratory if a 'wet lab' is being performed. Enclosed footwear may be canvas, leather, steel toed work boots, or even plastic bags securely taped around your feet. If you come to the laboratory and chemicals are being used (other than ink, pencil, paper, and dry erase chemicals for a dry lab), you will be dismissed from the laboratory and receive a grade of zero (0) for that experiment. There are NO MAKE-UP LABS, if you miss the experiment you automatically lose all points associated with that experiment. If we are doing a "dry lab" or continuing in lecture or review, you do not need to have your safety glasses, you will not need enclosed footwear for dry labs.
NO water bottles, soft drinks, or food is allowed in the laboratory. This is a safety violation that will result in your removal from the lab.
You should dress defensively for the laboratory. You are required to be covered from your neck to below your knees when performing an experiment in the chemistry laboratory. You are almost guaranteed that you will ruin at least one piece of clothing in the laboratory. If you wish, you may purchase an apron or an artist's smock (lab coat) to protect your clothes. You may also wish to bring and wear rubber, latex, or nitrile gloves in lab. Gloves may help in preventing skin irritation, on the down side, gloves also tend to increase the unknowing transport of chemicals to your clothing and increase the occurrence of holes in your clothes.
You can expect to cover at least 1 chapter per week and should use this as a guideline to plan ahead. You should have read all of the topics to be covered in each lecture before coming to class. This material is considered to be fair game for the scheduled exams and the final.
A CHEM 2423 eCampus homepage has been created and can be found at the following Internet address https://ecampus.blinn.edu. This site contains the course information sheet, homework assignments, and any additional lecture notes for the chapter being covered. Note: Simply studying the notes or old PowerPoint lectures provided on eCampus will not be sufficient to ensure a good grade in this course.
If you have a complaint about your class, you should first request a conference with your instructor to try and resolve the problems or issues. If the problems or issues cannot be resolved at the instructor level, you should request a conference with the Chemistry Coordinator, Mr. Thomas Jose, Health 252, email@example.com, 979-209-7484. If the complaint still is not resolved, you should request a conference with the Assistant Division Chair for Chemistry and Biology, Dr. Lee Don Bienski, Science 231, firstname.lastname@example.org, 979-209-7263. If this still does not resolve the complaint, you should then request a conference with Science Division Chair, Mr. Dwight Bohlmeyer, Science 241, email@example.com, 979-209-7506. Failure to follow the chain of command will result in a delay in the resolution of your problem
