Safety Glasses: Approved safety glasses are to be worn at all times while inside the organic chemistry laboratory. Even if you are not actually carrying out an experiment, a person near you might have an accident that could endanger your eyes. Even dish washing may be hazardous. Contact lenses are not to be worn inside the organic chemistry laboratory even when safety glasses are worn over them because they can trap harmful vapors against the eye. Attendance: Laboratory will be held on Tuesday and Thursday of each week in Laboratory 213, Wishnick Hall. 9:00 am to 12:40 pm. There will be no make-up laboratories. Required Texts: (1) "Operational Organic Chemistry: A Problem-Solving Approach to the Laboratory Course" by J. W. Lehman, Prentice Hall : New Jersey, 1999. (2) Bound Laboratory Notebook Experiments: There will be ten (11) experiments. Your grade for each experiment is based on your performance in four (4) areas: 1. Quizzes 2. Laboratory Techniques 3. Laboratory Reports 4. Products Quizzes: There will be ten (10) quizzes. Each quiz will consist of 5-10 questions taken from the required readings and experimental procedures for each experiment. Quizzes are given at the beginning of each laboratory period and there would be no make ups. Half of the each quiz is on the experiment that you have finished the pervious week and the other half is on the experiment that you are going to perform that day. So you should read the procedures and reading assignments before you enter to the laboratory. Laboratory Technique: You will be graded ten (10) times for your laboratory techniques (once for each experiment you perform). The basis for this grade are: (1) Adequately Prepared Laboratory Notebook, (2) Neat and Orderly Experimental Set-Up, (3) Being Prepared in Performing the Experiments. See: Handout on "Format for Laboratory Notebooks" Laboratory Reports: You must submit ten (10) Laboratory reports (one for each experiment). Each report should be no more than two pages. The reports are due the week after the experiment has been completed. Late laboratory reports will not be accepted. See: Handout on "Format for Laboratory Reports" Products: You must submit 9 products for grading. The grading is based on purity (65%, appearance (10%) , and yield (25%). See: Handout on "Format for Properly Labeling Products"
Grading:
Quizzes 100 points Technique 100 points Reports 100 points Products 90 points -------------------------------- Total 390 points Grading: The total points will be divide by 1.95 and will be added to your total lecture score (200 points max for laboratory).

| * Reading assignments are taken from the required laboratory book. The abbreviation "OP" stands for laboratory operation. You are required to read the description of the laboratory operations employed with each experiment. Descriptions of the laboratory operations (numbered in sequence from OP-1 to OP-37) can be found on pages 573-761 of the text. | |||
