Assertion : Acetaldehyde is more reactiv...

Assertion : Acetaldehyde is more reactive than acetone in nucleophilic addition reactions.
Reason Two alkyl groups in acetone reduce the electrophilicity of the carbon.

Text Solution

Verified by Experts

Acetone is less reactive towards nucleophilic addition reactions as compared to acetadehyde due to greater-I effect of the two -`CH_(3)` group and also greater steric hindrance offered to the attacking nucleophile. For details, consult section 8.
