Vedclass · Answer

(C) The reactivity of carbonyl compounds towards nucleophilic addition depends on the electrophilicity of the carbonyl carbon.Alkyl groups are electron-donating due to the $+I$ effect,which decreases the positive charge on the carbonyl carbon and increases steric hindrance.As the number of alkyl groups attached to the carbonyl carbon increases,the reactivity towards nucleophilic addition decreases.Therefore,the order of reactivity is:$HCHO (I) > CH_3CHO (II) > CH_3COCH_3 (III)$

The reactivity towards nucleophilic addition reaction of
$(I) HCHO$,
$(II) CH_3CHO$,
$(III) CH_3COCH_3$ is
