Aldehydes are more reactive than ketones towards nucleophilic addition reaction

Asked by admin @ 07/08/2021 in Chemistry viewed by 256 People

Answered by admin @ 07/08/2021

Answer:

Aldehydes are generally more reactive than ketones in nucleophilic addition reactions due to steric and electronic reasons. Sterically, the presence of two relatively large substituents in ketones hinders the approach of nucleophile to carbonyl carbon than in aldehydes having only one such substituent
