Q.1. Give reasons for the following: a) p-xylene is susceptible that toluene towards free radical halogenation. b) Para and meta cresols are obtained in equal amounts when para-bromo toluene is treated with NaOH at high temperatures. c) Sulphonation is a reversible process Rates assured....

For sulphonation ,the activation energy for the forward and backward reactions are comparable...so the reaction can proceed in any direction....
i dont think there is any need to go deep into the reasons as far as IITJEE syllabus is concerned..

sulphonation of benzene is highly rev. in sulphonation SO3H gets attached to the ring. SO3- is a very good leaving group(stable)and ther4 it leave the ring leading to desulphonation. as here SO3 is the electroplhile

1)p-xylene reacts more easily than toluene becoz the radical so formed during the reaction gets stabilized by hyperconjugation+resonance in p-xylyne(in comparision to only resonace in toluene)
