Organic Chemistry Laboratory I - NSC17, 2 credits  Fall 2010

Instructor Allison Turner (Sci 206), Todd Smith (Sci 110)
Location Science 112
Day & Time Tuesday, 1:30-4:50
Protocols & operations from Microscale operational organic chemistry, J.W. Lehman

Course Description

In the laboratory you will apply the same concepts and analytical skills we use in the classroom. You will continue to hone problem-solving skills and become familiar with organic chemistry laboratory equipment and procedures. Laboratory sessions will be designed to allow you to explore ideas discussed in class through structured protocols and through more open-ended inquiry. Initial labs will guide you through the isolation and identification of various compounds of interest, preparing you for your own more in-depth research.

By using these techniques you will become comfortable working in a laboratory and

familiar with techniques commonly used by organic chemists.

Grading Policy

Students are expected to complete all reading assignments, and must attend all lab sessions. There will be two lab reports due over the course of the semester. The first report, based on one of the first two labs, is worth 25 points. The second, based on your independent project, is worth 35 points. You will also keep a lab notebook (see below), which will be evaluated at the end of the semester, and will be worth 20 points. The final portion of your grade will be based on your preparation for and performance in the lab. The grade received in the course will be the ratio of points earned over points possible: 90% & above = A, 80-89% = B, 70-79% = C, 60-69% = D. Diligent and conscientious participation in lab and on assignments will boost borderline grades to the higher grade.

Attendance policy: you must attend all laboratory sessions. There will be no lab make-ups. If you miss a lab you must write a 2- page paper on the topic that was explored in that particular lab session – it is your responsibility to write this paper and submit it by the next week’s lab. However, if you miss more than one lab you will not be able to earn an A for the class.

Laboratory Notebooks

For this course you will need a dedicated laboratory notebook. For each laboratory session you should record the purpose of the lab, what you did in the lab, and what you found. Your notebook is a place to keep detailed notes of these activities in a format that will allow you to make sense of your lab activities at a later date, e.g., when writing a lab report at 3 a.m.
