Vedclass · Answer

(B) Sulphonation is an electrophilic aromatic substitution reaction. The rate of this reaction depends on the electron density of the benzene ring. Alkyl groups are electron-donating groups ($+I$ effect and hyperconjugation) that increase the electron density of the ring,thereby activating it towards electrophilic substitution.The activating power of alkyl groups follows the order: $CH_3- > CH_3CH_2- > (CH_3)_2CH- > (CH_3)_3C-$.This is because the primary alkyl group (methyl) has the most effective hyperconjugation and the least steric hindrance compared to the bulky tertiary alkyl group (tert-butyl). Therefore,toluene $(CH_3-C_6H_5)$ will undergo sulphonation at the fastest rate.
