Question

α-hydrogen of Aldehyde/ketones are acidic why?​

Answer 1

Explanation:

Alpha hydrogen is nothing but the hydrogen atom attached to the alpha carbon atom,which in turn is attached to the carbonyl carbon. ... Hence alpha hydrogen atoms in aldehydes and ketones are acidic in nature. As alpha hydrogen is acidic,bases can easily remove acidic hydrogen to form intermediate carbanions.

Answer 2

Answer:

The acidic property of α-hydrogen in aldehydes and ketones is because of the high electron-withdrawing capacity of the carbonyl group and resonance stabilization of the conjugate base.
