Question

Chlorination of benzene in the presence of halogen carrier is an example of (A) aromatic nucleophilic substitution (B) aromatic electrophilic substitution (C) aromatic nucleophilic addition (D) aromatic electrophilic addition

Tardigrade Admin · Accepted Answer

The chlorination of benzene in the presence of halogen carrier (ie, Lewis acid) is an example of aromatic electrophilic substitution. Mechanism of chlorination is as follows

Cl - Cl + (ha l o g e n c a rr i er) F e C l_{3} (e l ec t ro p hi l e) C l^{+}

+ F e C l_{4}^{-}

The chlorination of benzene in the presence of halogen carrier (ie, Lewis acid) is an example of aromatic electrophilic substitution. Mechanism of chlorination is as follows
$Cl - Cl + (ha l o g e n c a rr i er) F e C l_{3} (e l ec t ro p hi l e) C l^{+}$ $+ F e C l_{4}^{-}$
