Chlorobenzene is formed by reaction of chlorine with benzene in the presence of $A l C l_{3}$ . Which of the following species attacks the benzene ring in this reaction?

(a) $C l^{-}$ (b) $C l^{+}$ (c) $A l C l_{3}$ (d) $[A l C l_{4}]^{-}$

Solution

Answer: (b) $C l^{+}$

In this reaction, $A l C l_{3}$ is a catalyst which activate the chlorine molecule to show heterolytic cleavage. $A l C l_{3}$ is electron deficient molecule and form $[A l C l_{4}]^{-}$ and $C l^{+}$ when reacts with $C l_{2}$ . This $C l^{+}$ electrophile attacks on electron rich benzene ring.

$A l C l_{3} + C l_{2} \to [A l C l_{4}]^{-} + C l^{+}$
