Which of the following arrangements with respect to their reactivity in nucleophilic addition reaction is correct?

(1)benzaldehyde < acetophenone < p-nitrobenzaldehyde < p-tolualdehyde
(2)acetophenone < benzaldehyde < p-tolualdehyde < p-nitrobenzaldehyde
(3)acetophenone < p-tolualdehyde < benzaldehyde < p-nitrobenzaldehydeCorrect
(4)p-nitrobenzaldehyde < benzaldehyde < p-tolualdehyde < acetophenone

Answer: (3)

Solution

Steric hindrance decreases reactivity (acetophenone has extra methyl group vs aldehydes) and
