Vedclass · Answer

(B) Electrophilic substitution reactions are faster in compounds with electron-donating groups (activating groups) and slower in compounds with electron-withdrawing groups (deactivating groups) compared to benzene.$C_6H_5CH_3$ (Toluene) has a methyl group,which is electron-donating ($+I$ effect).$C_6H_5OH$ (Phenol) and $C_6H_5NH_2$ (Aniline) have $-OH$ and $-NH_2$ groups respectively,which are strongly activating due to resonance ($+M$ effect).$C_6H_5NO_2$ (Nitrobenzene) has a $-NO_2$ group,which is a strong electron-withdrawing group due to its $-I$ and $-M$ effects,making the ring electron-deficient and thus less reactive towards electrophiles than benzene.
