Cholorobenzene is formed by reaction of ...

Cholorobenzene 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?

A

`Cl^(-)`

B

`Cl^(+)`

C

`AlCl_(3)`

D

`[AlCl_(4)]^(-)`

Text Solution

Verified by Experts

The correct Answer is:
B
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
