Vedclass · Accepted Answer

Toluene

Vedclass · Answer

(C) The rate of electrophilic aromatic substitution,such as sulphonation,depends on the electron density of the benzene ring. $CH_3$ group in Toluene is an electron-donating group ($+I$ effect and hyperconjugation),which increases the electron density of the benzene ring,making it more reactive towards electrophiles compared to Benzene,Chlorobenzene (deactivating),and Nitrobenzene (strongly deactivating). Therefore,Toluene undergoes sulphonation most easily.
