JEE MAIN - Chemistry (2025 - 24th January Morning Shift - No. 15)
Which of the following arrangements with respect to their reactivity in nucleophilic addition reaction is correct?
acetophenone $<$ benzaldehyde $<$ p-tolualdehyde $<$ p- nitrobenzaldehyde
acetophenone $<$ p-tolualdehyde $<$ benzaldehyde $<$ p- nitrobenzaldehyde
p- nitrobenzaldehyde $<$ benzaldehyde $<$ p-tolualdehyde $<$ acetophenone
benzaldehyde $<$ acetophenone $<$ p- nitrobenzaldehyde $<$ p-tolualdehyde
Explanation
The rate of nucleophilic addition decreased due to steric crowding around carbonyl carbon \& increased by electron withdrawing group if the steric crowding is same hence the reactivity towards nucleophilic addition will be
