Vedclass · Answer

(B) The reaction of benzene with isobutylene in the presence of $H_2SO_4$ is an electrophilic aromatic substitution reaction (Friedel-Crafts alkylation). $1$. $H_2SO_4$ protonates isobutylene $(CH_3)_2C=CH_2$ to form a stable tert-butyl carbocation $(CH_3)_3C^+$. $2$. This carbocation acts as an electrophile and attacks the benzene ring. $3$. The final product formed is tert-butylbenzene.

The reaction of benzene with isobutylene in the presence of $H_2SO_4$ gives:
