Question

Explain why Aldehydes are more reactive than ketones towards nucleophilic attack. And who is more reactive Aldehydes or ketones towards electrophilic attack.

Answer 1

Aldehydes are more reactive than ketones towards nucleophilic addition reactions due to the following factors:
 
1. Aldehydes are less sterically hindered as compared to ketones.
 
2. Aldehydes are more reactive as compared to ketones due to factors like hyperconjugation. 

3. Carbonyl group in an aldehyde is more polar than the carbonyl group of ketones. 

Answer 2

Answer:

Aldehydes are usually more reactive toward nucleophilic substitutions than ketones because of both steric and electronic effects. In aldehydes, the relatively small hydrogen atom is attached to one side of the carbonyl group, while a larger R group is affixed to the other side.
