Safety: Safety glasses are to be worn at all times in the laboratory. A knee-length flame-resistant lab coat (blue) must be worn while in lab (lab aprons and cotton lab coats are not acceptable ). Contact lenses should not be worn in the laboratory. Low-heeled shoes, which cover the toe and instep, must be worn at all times while in the laboratory. Clogs, sandals, cloth-top sneakers and narrow-base heels are not acceptable. Tennis shoes will suffice. Shorts and short skirts are not allowed. Pants or skirts that cover the ankles are required. Hair that is shoulders length or longer has to be tied back. Food, chewing gum and cell phones are not allowed in the laboratory. Any student under the care of a physician for either acute or chronic medical reasons (i.e. diabetes, essential hypertension, epilepsy, pulmonary disease) and/or is pregnant should advise his/her physician that s/he is taking organic chemistry lab. Also, the student should advise the lab instructor immediately.
Glass and syringe needles are never to be disposed of in the regular trash receptacles (this poses a hazard to the janitor). All glass waste and syringe needles go into the glass waste containers (blue box labeled glass waste). Failure to observe this rule will result in dismissal from the course. Any student whose deliberate or negligent acts or omissions endanger his/her own safety or that of others may be expelled from the laboratory. Laboratory safety will be discussed at the first lab lecture.
Wait Listed: If you are wait-listed, wait inside the lab section you are wait-listed for. If there is space you will be added. The department (Denise Mantonya, Young 4006) will add you if you are written in on the class roster (make certain that you are written in). Regardless, it is your responsibility to make certain that you have been added to URSA. If your account does not show the enrollment by the thursday of the second week, contact the instructor before the last day to add. The department does not use PTE numbers anymore.
Text: Course Reader Chem 30BL; "A Survival Kit for the O=Chem Lab", Exam Collection for Chem 30BL (Spring 2016 edition, $65) (available at Course reader Materials); Mohrig, Techniques in Organic Chemistry, 4th edition (recommended).; Brown and Foote, Organic Chemistry, 7th edition (or a comparable O-Chem text book).
Lab Notebook: Bound with duplicate removable pages, safety glasses, nitrile gloves and lab coat are mandatory and are available from Young 1275, the ASUCLA bookstore or the medical bookstore.
Handouts and Lecture notes: Additional lecture handouts will be available on the course web site. If you are unable to attend lecture then you need to make arrangements with a classmate or friend for those days notes and handouts. The lecture will also be podcasted. It is advisable to consult the course web site for additional information about techniques used in the lab (tutorials and video material). Note that the instructor does not use the CCLE website since he has his own website on which materials will be posted.
Academic Standards: Attendance to lecture is mandatory. You will be held responsible for all material covered during lecture. On occasion, adjustments to the course syllabus during lecture may be made (i.e., change of exam date, lecture material to be covered, etc.). An unexcused failure to attend lecture or to perform experiments on schedule or to submit timely experimental write-ups may have an out of proportion adverse effect on your course grade. In extreme cases, the student may receive an "F" for the course regardless of the point total.
Failure to perform an experiment will result in an "F"-grade for the course. In the case of an excused absence, the student will be allowed to makeup the experiment without penalty (if you are unable to makeup the experiment you will receive an Incomplete). Falsely representing that an experiment has been performed will be regarded as equivalent to cheating on an exam. Cheating will not be tolerated and be reported to the Dean.
Examination Policy: There will be no make-up exams or quizzes. No exams will be administered earlier than the scheduled exam time. (If you plan to take the final exam with the OSD, please make sure that you register with them asap. The instructor will not be able to accommodate any requests.) If the final exam is missed, the student should bring it to the immediate attention of the instructor. If the student has a bona fide reason then they will receive an incomplete for the course, otherwise, they will receive an automatic failure grade (F) for the entire quarter. An established incident of cheating will also result in an automatic failure grade (F) for the entire quarter. Students who are aware of cheating are encouraged to report such incidents. Securing a "recommendation" after a cheating incident at the University is, needless to say, awkward at best! Do not foolishly mortgage your professional future by cheating now. A course grade of incomplete (I) will be considered only for individual cases with exceptional extenuating cause. An incomplete will not be given in lieu of a failing grade.
Lab Preparation: You must be prepared for the experiment before you enter the lab if you wish to complete the experiment in the time allotted. There is no make-up time in the course and no space for you to work in other sections. Make sure to study the pertinent sections in the text and then prepare a summary or flow chart of the procedures that will be performed in the laboratory. Your teaching assistant will check your pre-lab preparation at the start of the lab. An open laboratory text (or Xerox copies of the laboratory procedure) will result in an automatic 5-point deduction. For purposes of safety, lack of preparation will result in dismissal from that lab period and an automatic zero for the lab.
Grading
Following is the point-break down for each lab meeting.
IN-LAB QUIZ will cover previous and current meeting’s experiment; 20 points/lab (closed book and notes; Note: Lowest or missed (regardless of the excuse) quiz will be dropped. Address all specific questions about the quizzes towards your TA, because s/he writes and grades the quiz).
ONLINE QUIZZES (currently 7, 10 points/each)
INFRARED ASSIGNMENT (40 points, required, due by April 8, 2016
at 12 pm)
LIBRARY ASSIGNMENT (15 points, required, due by April 15, 2016 at 12 pm)
·
COMPUTER ASSIGNMENT
(meeting 4, 15 points
EXTRA CREDIT PROJECT (20 points)
Pre-write-up: Title, date, purpose, introduction, procedure,
literature spectra, reference(s), answers to assigned questions (5 points each)
Post-write-up: Observations, results, discussion of spectra and other obtained data on final product or intermediates, conclusions (5 points)
Turnitin Course ID for Spring 2016: 12241485
TA/INSTRUCTOR EVALUATION (10 points/lab)
(TA/Instructor evaluation points will be assigned at the end of the course. Lab safety, product evaluation, in-lab evaluation, preparedness and end of quarter lab notebook evaluation are all criteria in making this evaluation. On average the student can expect to receive 7-8 points/meeting)
LAB NOTEBOOK (end of quarter evaluation, 20 points)
(Note: must be bound with consecutively numbered pages and in ink; if a bound lab notebook is not used (i.e., spiral notebook; word processing generated report; ring note book) then no points will be given; if a table of contents is missing then there will be a 10 point deduction; missing homework assignments will result in deduction of 4 points each; notebooks that are well-organized and complete will receive full credit. Failure to hand in a lab notebook will at best result in an incomplete and in unexcused cases will result in a non passing grade.)
FINAL EXAM (June 10, 2016 at 8:00-11:00 am, room tba, 210
points)
TOTAL ~670 points
Grade | Point range | Grade | Point range |
A | 580-670 points | C+ | 480-499 points |
A- | 560-579 points | C | 460-479 points |
B+ | 540-559 points | C- | 440-459 points |
B | 520-539 points | D | 390-439 points |
B- | 500-519 points | F | <390 points |
Note: This is an approximate grade scale after the in-lab and the exam grades have been adjusted to the match the grade scale (usually requires deductions of the in-lab score). Extremely poor performance in either portion of the course (in-lab or final exam) will have an adverse effect on the overall grade (=final grade below "C-"-grade). Failure to pass the final exam (<105 points) results in an automatic grade below "C-"-grade. Under normal circumstances (final exam average= "B-"-grade), the average grade is the lower end of a "B-"-grade.
Individual Housekeeping:The laboratory can function smoothly only if left clean at the end of each lab. Poor housekeeping will result in a grading penalty of 3 points for each infraction. Dumping of hazardous material in trash receptacles or in sinks is ground for dismissal from the course. On leaving the lab, after an experiment, each student at his/her station and hood used should ensure the following:
1. Hot plate is unplugged and cord is neatly coiled around plate after cooling. if not then -3 points
2. Spills are wiped up and balances are swept clean. if not then -3 points
3. Work bench area needs to be sponged down at the end of lab if not then -3 points
4. The sink is free of glass, paper towels, corks and other insoluble solid refuse. Such material belongs in the appropriate waste container. if not then -3 points

During you assigned meeting, you will be responsible for making sure that the lab is left clean. A clean-up checklist can be obtained from your TA or the storeroom. If any portion of the lab is left unclean (your lab or instrumentation room), then a 4-5 page report paper (single space, font size 12, font type times, 1 inch margin on all sides) will be assigned to all the individuals responsible for that meeting. The paper is worth 20 points and the instructor will select the topic of the paper.
Waste Disposal: All chemical waste goes into the appropriate waste containers supplied in the hood. If you are not sure of how to dispose of a chemical, ask your TA or stockroom personnel for help. All products are to be stored in a labeled container. All vials (containers) containing product must be labeled correctly (name, product, and date). Failure to correctly label a vial will result in a 5-point deduction.
Breakage & Check-out: The security of your locker is your responsibility. You will be charged for broken or missing items; your desk must be fully stocked on checkout. If you fail to checkout of a desk you have drawn, you will be assessed a $25 abandoned desk penalty in addition to charges for missing or broken equipment.
