Tardigrade Admin · Accepted Answer

During chlorination of benzene, anhydrous

A lC l_{3}

, being a Lewis acid helps in generation of the electrophile

C l^{+}

by combining with the attacking reagent.
The electrophile

C l^{+}

attacks the benzene ring in this reaction.

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

$C l^{-}$

$C l^{+}$

$A lC l_{3}$

$[A lC l_{4}]^{-}$

During chlorination of benzene, anhydrous $A lC l_{3}$ , being a Lewis acid helps in generation of the electrophile $C l^{+}$ by combining with the attacking reagent.
The electrophile $C l^{+}$ attacks the benzene ring in this reaction.
