Vedclass · Answer

(A) Reactivity towards nucleophilic addition reactions depends on steric and electronic factors. As the number and size of alkyl groups attached to the carbonyl carbon increase,the reactivity decreases due to the $+I$ effect (which reduces the electrophilicity of the carbonyl carbon) and increased steric hindrance. $HCHO$ has no alkyl groups,$CH_3CHO$ has one methyl group,$CH_3COCH_3$ has two methyl groups,and $CH_3CH_2COCH_2CH_3$ has two larger ethyl groups. Therefore,the correct decreasing order of reactivity is: $I > II > III > IV$.

Arrange the following compounds in decreasing order of reactivity towards nucleophilic addition reactions:
$(I) \ HCHO$,$(II) \ CH_3CHO$,$(III) \ CH_3COCH_3$,$(IV) \ CH_3CH_2COCH_2CH_3$
