Vedclass · Answer

(B) $1$. Nucleophilic addition reactions in carbonyl compounds depend on the electrophilicity of the carbonyl carbon and steric hindrance.$2$. Aldehydes have one alkyl group and one hydrogen atom attached to the carbonyl carbon, whereas ketones have two alkyl groups.$3$. Alkyl groups are electron-donating ($+I$ effect), which reduces the positive charge (electrophilicity) on the carbonyl carbon.$4$. Ketones have two such groups, making them less electrophilic than aldehydes.$5$. Additionally, two alkyl groups in ketones create more steric hindrance compared to one alkyl group and one small hydrogen atom in aldehydes, making the approach of the nucleophile more difficult in ketones.

Aldehydes are more reactive than ketones towards nucleophilic attack because of?
