Question
Match the compounds mentioned in List-I with their properties mentioned in List-II. List - I: (P) p-xylene (1,4-dimethylbenzene) (Q) 4-methyl-1,3-dinitrobenzene with CN substituent (R) resorcinol (1,3-dihydroxybenzene) (S) p-dichlorobenzene (1,4-dichlorobenzene) List - II: (1) Forms one monosubstituted product in electrophilic substitution reactions. (2) Forms more than one monosubstituted product in electrophilic substitution reactions (3) More reactive than benzene towards EAS reaction (4) Less reactive than benzene towards EAS reaction (5) The substituents exert -I as well as +R effect
💡 Solution & Explanation
(A) forms monosubstituted product, it is more reactive than benzene due to presence two activating CH3 groups. (B) forms monosubstituted product because one position is meta w.r.t electron withdrawing groups and para with respect to CH3 group. It is less reactive than benzene due to two deactivating and one activating group. (C) forms more than one monosubstituted product and is more reactive than benzene due to two activating OH groups. The OH groups exert –I and +R effect. (D) forms more than one monosubstituted product and is less reactive than benzene. The Cl atoms exert –I as well as +R effect.
