Benzene when reacts with Cl2 in the presence of AlCl3 forms chlorobenzene. One of the hydrogen of benzene gets substituted by Cl+ and forms chlorobenzene along with HCl as byproduct. The lewis acid acts as a catalyst in the reaction. It forms an anionic complex with Cl- from Cl2 to form AlCl4- and gives Cl+.

hey mate here is your answer
Benzene undergoes electrophilic substitution reactions in the presence of Lewis acids like AlCl3 and FeCl3. Benzene when reacts with Cl2 in the presence of AlCl3 forms chlorobenzene. One of the hydrogen of benzene gets substituted by Cl+ and forms chlorobenzene along with HCl as byproduct.
The lewis acid acts as a catalyst in the reaction. It forms an anionic complex with Cl- from Cl2 to form AlCl4- and gives Cl+. This Cl+ attacks on benzene as an electrophile and forms chlorobenzene and H+. AlCl4- combines with H+ to form HCl and AlCl3 is recovered back.
Hope this will help you
