CHEM 3341: Laboratory for Organic Chemistry II

This lab course is for biochemistry and non-chemistry majors. Chem 3341 is a continuation of Chem 3321, Organic Chemistry I Lab. The laboratory techniques learned in 3321 are used to carry out reactions in aromatic substitution, organometallic chemistry, oxidation and reduction chemistry, esterifications, aldol condensations, and Wittig chemistry. A significant portion of the semester is devoted to separating and determining the structure of unknown organic compounds, as well as verifying the identification of compounds synthesized in lab.

The course syllabus and TA office hours and emails are available on this website. Course documents will be posted on Canvas.
