Nucleophilic addition reaction will be most favoured in
A
CH3CHO
B
C
(CH3)2C $$=$$ O
D
CH3CH2CHO
Explanation
Aldehydes are more reactive than ketones
due to +I effect of –CH3
group. There are two –CH3
group in acetone which reduces +ve charge
density on carbon atom of carbonyl group. More
hindered carbonyl group too becomes less
