Vedclass · Answer

(B) The reactivity of carbonyl compounds towards nucleophilic addition is governed by two factors: steric hindrance and electronic effects.Alkyl groups are electron-donating ($+I$ effect),which decreases the electrophilicity of the carbonyl carbon.Additionally,alkyl groups increase steric hindrance,making it difficult for the nucleophile to attack.$HCHO$ has two hydrogen atoms (no alkyl groups),$CH_3CHO$ has one methyl group,and $CH_3COCH_3$ has two methyl groups.Therefore,the reactivity order is $HCHO > CH_3CHO > CH_3COCH_3$.

Among the following,the order of reactivity towards nucleophilic addition is:
