18.31 Aldehydes that have no a hydrogen undergo an intermolecular oxidation-reduction called the Cannizzaro reaction when the are treated with concentrated base. An example is the following reaction of benzaldehyde: oboros H HỌ OH 2 H₂O + (a) When the reaction is carried out in D₂O, the benzyl alcohol that is isolated contains no deuterium bound to carbon. It is CH-CH₂OD. What does this suggest about the mechanism for the reaction? (b) When (CH₂)₂CHCHO and Ba(OH)₂/H₂O are heated in a sealed tube, the reaction produces only (CH₂)2CHCH₂OH and [(CH3)2CHCO₂]₂Ba. Provide an explanation for the formation of these products.
