Which one is most reactive towards nucleophilic addition reaction?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
Ketones are less reactive than aldehdyes whereas electron-withdrawing groups (i.e., `NO_(2)`) increase the reactivity while electron donating (i.e., `CH_(3)`)decrease the reactivity of aromatic aldehydes towards nucleophilic addition reactions. The optioin (d) is correct.
