Khoi Nguyen 10-1-07 Lab #4 Title: Reduction of Camphor as a Carbonyl Compound Introduction In this experiment, a reduction of a carbonyl compound, camphor, will be carried out using sodium borohydride as the reducing agent. Sodium borohydride is a source of hydrides, which undergo nucleophilic addition reactions with ketones and aldehydes to produce alcohols. The products of the reduction are isoborneol and borneol in a 6:1 ratio, respectively. The filtered product will be massed and the percent yield will be determined. Also, an IR spectrum will be obtained for the isoborneol in order to analyze any significant absorptions. Table of Reagents mol. wt. (g/mol) density (g/mL) camphor 152.24 methanol 32.04 0.79 sodium borohydride 37.83 isoborneol 154.25 borneol 154.25 Safety Information - methanol is toxic to the optic nerve Procedure 1. Dissolved 0.200 g of camphor in 2 mL of methanol in a 5 mL vial. Added 0.100 g of NaBH 4 to the solution. 2.
