Q.
Choose the correct option regarding the comparison of reactivity of benzaldehyde and propanal.
Aldehydes Ketones and Carboxylic Acids
Solution:
The $C$-atom of the carbonyl group of benzaldehyde is less electrophilic than $C$-atom of the carbonyl group present in propanal due to resonance. Hence, it is less reactive than propanal towards nucleophilic addition reaction.
