This experiment utilized the reaction of benzil + NaBH4 / H2O to give meso-hydrobenzoin. NaBH4 is utilized in this reduction to add a hydride ion to the organic substrate, benzil. NaBH4 and ethanol are utilized in the reaction to add hydrogen to a carbonyl group and the OH hydrogen comes from the ethanol. The mechanism is a reduction. Demonstrate the mechanism and all steps involved in the reaction.
