CHEM 3321: Laboratory for Organic Chemistry I

This lab course is for biochemistry and non-chemistry majors. A large part of Chem 3321 is spent learning techniques in organic chemistry, including TLC, distillation, extraction, crystallization, and IR spectroscopy. Once these techniques are mastered, they are employed in the final four labs of the semester. Two laboratory periods are devoted to working with molecular models sets to study nomenclature, conformational analysis, and stereochemistry.

TA office hours and emails are posted here.
