`CH_3-underset(CH_3)underset(|)overset(CH_3)overset(|)C-CHO` shows Cannizaro's reaction due to

Options

A. Carbon is bounded by 3 methyl groups
B. Absence of `alpha`-hydrogen atom
C. Due to steric effect
D. None of these

Answer

B

Explanation

Aldehydes that have no `alpha`-hydrogen atom give Cannizzaro reaction, in which two molecule of aldehyde in presence of 50% aqueous NaOH , gives one molecule of alcohol and one molecule of sodium salt of acid.
