CHM 325 Organic I This is an introductory course that introduces some techniques (which in our new program has some of these moved to the new techniques course) and then moves onto reaction chemistry by functional group. IR spectroscopy is introduced and all the reactions require the student to also run their own IR’s, TLC’s and mp/bp’s Experiment #1 An Introduction to Thin-Layer Chromatography (TLC) Shows the student how to stretch pipettes into capillaries and how to run qualitative TLC’s Experiment #2 Melting Point and Boiling Point Students learn how to use Thiele tubes for mp’s and also two methods for bp determinations Experiment #3 Recrystallization The complete process of recrystallization of benzoic acid is illustrated. Experiment #4 Simple Distillation A simple distillation is setup and run for low boiling liquids such as methanol Experiment #5 Fractional Distillation The fractioning column is used to help separate two liquids such as methanol and water. Experiment #6 Introduction to the Separatory Funnel and Extraction with Solvent Benzil and benzoic acid are separated using the separatory funnel. Experiment #7 Bromination of an Alkene 1.1 equiv. Br 2 in CH 2 Cl 2 Br Br
