Kinetic Analysis of Ester Hydrolysis

A two-week multi-step experiment that introduces students to mechanistic organic chemistry and substituent effects. A simple preparation of differentially substituted para-nitrophenyl benzoates is followed by ester hydrolysis with monitoring by UV-Vis spectroscopy to provide rate data for the reaction.

Forensic analysis of analgesics by TLC

An introductory laboratory on the identification of analgesics in an unknown sample. Ideal for the first week of an organic chemistry sequence to get students familiar with their surroundings. Students extract, isolate, and perform thin layer chromatography on aspirin, acetominophen, or ibuprofen.
