Cannizzaro's reaction is an example of auto oxidation
1 it is a typical reaction of aliphatic aldehyde
2 it is a reaction answered by only aldehydes containing \(\alpha\)-hydrogen
3 it is a reaction answered only by aromatic aldehydes
4 it is a reaction answered by aldehydes.
Explanation:
(None) Aldehydes, which do not contain an\(\alpha\)-hydrogen atom undergoes Cannizaro reaction.
