Electrophilic substitution reaction

Vedclass · Answer

(B) The reaction involved is an electrophilic aromatic substitution.In the presence of $FeCl_{3}$ (a Lewis acid) and in the dark,the halogen $(X_{2})$ reacts to generate an electrophile $(X^{+})$.This electrophile attacks the benzene ring of toluene.Since the methyl group $(-CH_{3})$ is an ortho/para-directing group due to its $+I$ effect and hyperconjugation,the electrophilic substitution occurs primarily at the ortho and para positions to yield ortho and para-halotoluene.

Toluene reacts with halogen in the presence of iron$(III)$ chloride to give ortho and para halo compounds. The reaction is:
