Text Solution

Verified by Experts

The correct Answer is:
B
Benzaldehyde on treatment with `50%` aqueous ethonolic alkali sodium undergoes Cannizzaro's reaction like `HCHO` (on `alpha`- hydrogen atom), i.e., one molecule is oxidised and one is reduced with the formation of benzoic acid and benzyl alcohol respectvely.
