Q. Nucleophilic addition reaction will be most favoured in :
A) CH₃–CH₂–CH₂–CO–CH₃
B) (CH₃)₂C=O
C) CH₃CH₂CHO
D) CH₃CHO
Explanation
[Solution from source] Aldehydes are more reactive than ketones towards nucleophiles because they have less steric hindrance and only one electron-releasing alkyl group. Among the aldehydes, CH₃CHO has a smaller alkyl group than CH₃CH₂CHO, so it reacts most readily. Both ketones are less reactive. Answer (4).
