Q.
Assertion (A) $\alpha$-hydrogen atoms of carbonyl compounds are acidic.
Reason (R) The strong electron releasing effect of the carbonyl group make the stabilisation of the conjugate base by the resonance.
Aldehydes Ketones and Carboxylic Acids
Solution:
The acidity of $\alpha$-hydrogen atoms of carbonyl compounds is due to the strong electron withdrawing effect of the carbonyl group and resonance stabilisation of the conjugate base.
