Vedclass · Answer

(D) The reactivity towards electrophilic substitution depends on the electron density of the benzene ring.$A$ is benzene (reference).$B$ is toluene ($-CH_3$ group): It shows $+M$ (hyperconjugation) and $+I$ effects,which increase electron density,making it more reactive than benzene.$C$ is chlorobenzene ($-Cl$ group): It shows $+M$ and $-I$ effects. The $-I$ effect dominates,making it less reactive than benzene.$D$ is nitrobenzene ($-NO_2$ group): It shows $-M$ and $-I$ effects,which strongly decrease electron density,making it the least reactive.Therefore,the order of reactivity is $B > A > C > D$.
