Solution
The correct option is A I>II>III>IV
Aldehydes are more reactive than ketones towards nucleophiles due to following reasons:
1. Aldehydes tend to be more reactive to nucleophilic addition than ketones due to less steric hinderance. Ketones have two alkyl groups attached to their carbonyl carbon while aldehydes only have one. This means nucleophiles have a less sterically hindered path when attacking the carbonyl carbon of an aldehyde.
2. Two alkyl groups in ketones reduce the electrophilicity of the carbonyl carbon more effectively than in aldehyde.
Hence, aldehydes are more reactive toward nucleophilic addition reactions than ketones.
As the number and the size of the alkyl group increases, reactivity decreases, Hence, the correct order of reactivity isI>II>III>IV
