Question

Chlorobenzene is formed by reaction of chlorine with benzene in the presence of \[\ce{AlCl3}\]. Which of the following species attacks the benzene ring in this reaction?

Options

• \[\ce{Cl-}\]

• \[\ce{Cl+}\]

• \[\ce{AlCl3}\]

• \[\ce{[AlCl4]-}\]

Answer 1

\[\ce{Cl+}\]

Explanation:

\[\ce{Cl-}\] is an electrophile formed by the followed reaction.

\[\ce{AlCl3 + Cl2 -> [AlCl4]- + Cl-}\]

\[\ce{Cl+}\] attacks the benzene ring to give chlorobenzene.
