Question

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]^(-)`

Answer 1

Correct Answer - B
During chlorination of benzene, anhydrous `AlCl_3`, being a Lewis acid helps in generation of the electrophile `Cl^(+)` by combining with the attacking reagent.
The electrophile `Cl^(+)` attacks the benzene ring in this reaction.
