In the chlorination of benzene with `Cl_(2)`, in the presence of anhydrous `FeCl_(3)` the electrophilic species that attacks the benzene ring

Options

A. `Cl^(+)`
B. `Cl-overset(+)(C)l-overset(-)(Fe)Cl_(3)-overset(-)`
C. `Cl^(-)`
D. `Cl`

Answer

B

Explanation

It seems unlikely that an actually free `Cl^(+)` ion is involved instead ferric chloride combines with `Cl_(2)` to form a complex from which chlorine is transferred without its electrons directly to the ring.
