Abstract
Liquid 2-chlorobenzaldehyde was converted, by grinding with potassium hydroxide pellets, into equimolar quantities of solid 2-chlorobenzoic acid and solid 2-chlorobenzyl alcohol in a Cannizzaro reaction. TLC, IR, and NMR experiments, using authentic samples for comparison, confirmed the identity and purity of the two products. Guided-inquiry pedagogy was employed as an instructional model for teaching this green chemistry laboratory to undergraduates who were responsible for partially designing their experiment.
