Answer:

Reaction products are shown below

Explanation:

  • In cannizaro reaction, benzaldehyde produces benzoic acid and benzyl alcohol through disproportion.
  • Here, a hydroxyl group first gives a nucleophilc addition at carbonyl center of benzaldehyde.
  • Then a hydride transfer takes place to another molecule of benzaldehyde
  • Thus, benzoic acid and benzyl alcohol are produced.
