Benzene reacts with iodine monochloride in presence of anhyd.

A lC l_{3}

to form iodobenzene.
Iodine monochloride reacts with anhyd

A lC l_{3}

to produce

I^{+}

which acts as electrophile and attacks the benzene ring.
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Note: Anhyd.

A lC l_{3}

acts as lewis acid catalyst.

A lC l_{3} + I Cl \to I^{+} + A lC l_{4}^{-}

C_{6} H_{6} + I^{+} \to C_{6} H_{5} - I + H^{+}
