Question

Cannizzaro's reaction is an example of auto oxidation.

• A. It is a typical reaction of aliphatic aldehyde.
• B. It is a reaction answered by all aldehyde.
• C. It is a reaction answered by only aldehydes which do not contain $\alpha$- hydrogen.
• D. It is a reaction answered only by aromatic aldehydes.

Answer 1

The correct option is C It is a reaction answered by only aldehydes which do not contain $\alpha$- hydrogen.

Cannizzaro's reaction is an example of auto oxidation. It is a reaction answered by only aldehydes lacking $\alpha -$ hydrogen in this reaction, one molecule is oxidized to carboxylic acid and other molecule is reduced to alcohol.
