TH 2:00-4:50 pm PL 310, PL 202
This course is required for chemistry majors
Summary of the course
1. Each team of two students will receive an unknown organic compound and identify it, using instrumental analysis, physical and chemical tests of the students' choice.
2. The team of students turns in a short written report, supporting the elucidated structure.
3. The instructor assigns to each team a compound that should be synthesized from the identified compound in several steps.
4. The team searches original chemistry literature for the appropriate synthetic procedures to solve the synthetic challenge from the part 3.
5. The team presents the proof of identity of the unknown compound and the found synthetic approach to the class, develops a detailed experimental plan, and turns it in for the instructor's approval.
6. The team advances toward synthesis of the target compound by the procedures selected in part 5, characterizes the final and all intermediate products, turns in the laboratory report and the synthesized compound to the instructor.
7. During the semester, each student learns all experimental techniques employed in the course including the ones not related to his (her) synthetic project.
8. Each student turns in the written final experimental report (synthetic project results plus learned procedures) to the instructor and presents it to the class.
Note: All compounds synthesized during this laboratory course, will be further used for research. No products will go to the waste.
This course is managed through d2L. If you have any technical questions regarding this software, direct your questions to your instructor or to the USD IT Helpdesk.

2. If you have a disability for which you are or may be requesting an accommodation, you are encouraged to contact both your instructor and the Director of the Office of Disability Services, (Service Center 199; 677-6389) as early as possible in the semester.
3. No credit can be given for a dishonest assignment. At the discretion of the instructor, a student caught engaging in any form of academic dishonesty may be:
Students who missed two or more laboratory periods without an excusable reason, may be dropped from the course by the instructor.
Grading: Your grade will be determined as follows: The total number of points, as listed below, will be calculated.
Letter grades will then be assigned on the basis of the percentage of points accumulated, with cutoffs no higher than listed below.
A– 90% percentile
Identification report (team prepared) is a written 1-2 pages explanation how the unknown compound wes explored, and how the experimental data support the suggested structure.
SCHEDULE OF CLASS SESSIONS
IF YOU HAVE QUESTIONS, ASK THEM. If you can not stop by you instructor's office during the office hours, make an appointment or just walk-in.
1. The Organic Chemistry Laboratory Survival Manual, 5th or later Edition (J.W.Zubrick)
2. Safety Glasses or Goggles: Must provide adequate front and side protection.
3. Laboratory Notebook: bound notebook; ca. 8" X 10". Spiral and loose-leaf notebooks are not acceptable.
2. Pregnant students are advised not to work in organic laboratories. If you are, suspect to be, or become pregnant, notify the instructor immediately.
3. Eating, drinking, chewing gum, etc, are prohibited in the laboratory.
4. Avoid getting chemicals on your skin. If you happen to do so, wash the affected area immediately. Avoid rubbing your eyes, etc. while in the laboratory. Wash your hands thorougly immediately after leaving the laboratory.
5. Know the location of all safety equipment and fire escapes.
6. Use the fume hood when directed to do so.
7. Do not performed unauthorized experiments or alter the designated procedure without obtaining permission.
8. Dress for the laboratory - Clothing worn in the laboratory should provide maximum protection. Open toed/heeled shoes, sandals, etc., and high heels/platforms are not permitted. Long hair must be tied or pinned back. Do not wear your favorite or (and) very expensive items, as they may be destroyed or permanently stained by some chemicals.
9. When lighting a burner, make sure there are no flammable solvents in the area.
10. Even though you are working carefully, don't assume you or someone else won't have an accident that could injure you.
11. Keep your laboratory bench and common areas (balances, hoods, etc.) clean and free of clutter at all times.
12. Report all accidents (cuts, burns, other injuries, spills, fires, explosions, etc.) to the instructor immediately.
1. Freedom in learning. Students are responsible for learning the content of any course of study in which they are enrolled. Under Board of Regents and University policy, student academic performance shall be evaluated solely on an academic basis and students should be free to take reasoned exception to the data or views offered in any course of study. Students who believe that an academic evaluation is unrelated to academic standards but is related instead to judgment of their personal opinion or conduct should contact the dean of the college which offers the class to initiate a review of the evaluation.
a. Given a zero for that assignment.
b. Allowed to rewrite and resubmit the assignment for credit.
c. Assigned a reduced grade for the course.
d. Dropped from the course.
e. Failed in the course.
