| Instructor: | Dr. Arlene Courtney, NS 112 |
| Course Description: | This laboratory meets twice weekly. You will study a number of different reactions including nucleophilic substitution, hydration, oxidation-reduction, Diels-Alder, and electrophilic aromatic substitution. The significant portion of this term will be spent learning how to identify unknown organic substances. At the end of the term, you will be given three unknown organic compounds which you will identify using qualitative organic testing. This require you to interpret experimental results, make decisions and demontrate critical thinking skills. |

Unknowns will be turned in on 3 x 5 index cards for grading. Laboratory attendance is manditory unless you have been previously excused for attendance at a university activity. Missed labs will result in a 5 point deduction from your laboratory grade. Attendance will be taken each period. You must be in the laboratory at the beginning of the laboratory period. There will be no working in the laboratoryAT ANY OTHER TIMES than the Thursday laboratory periods.
You MUST have a Chem Ticket with you when working in the laboratory.
|
Short quizzes will be given at the beginning of the laboratory period over the pre-lab reading for that day's experiment. For all the experiments in the first half of this course, if you have not studied the experiment in detail BEFORE coming to the laboratory, you will have difficulty completing the experiment.
You will deliver a poster presentation of the identification of one of your unknowns to the class during the last laboratory period. Your poster should outline all the steps that you carried out to determine the identity of your unknown and the conclusions that you were able to draw from each procedure. Sample posters from a previous class are located in the display case in the hall outside the organic lab room. You will be graded on the quality of your oral presentation as well as the visual and content quality of your poster.
