Chlorobenzene is formed by reaction of chlorine with benzene in the presence of `AlCl_(3)`. Which of the following species attacks the benzene ring in this reaction?

Options

A. `Cl^(-)`
B. `Cl^(+)`
C. `AlCl_(3)`
D. `[AlCl_(4)]^(-)`

Answer

B

Explanation

In this reaction, `AICl_(3)` is a catalyst which activate the chlorine malecule to show heterolytic cleavage. `AICl_(3)` is electron deficient molecule and form `AlCl_(4)^(-)`, and `Cl^(+)` when reacts with `Cl_(2)`. This `CI^(+)` electrophile attacks on electron rich benzene ring
