Options

A. Electrophilic elimination reaction
B. Electrophilic substitution reaction
C. Free radical addition reaction
D. Nucleophilic substitution reaction

Answer

B

Explanation

Toluene reacts with a halogen in the presence of iron (III) chloride giving ortho and para halo compounds. The reaction is electrophilic substitution reaction
It has the following mechanism
`Cl-Cl overset(FeCl_3)(rarr)FeCl_4^(-)+Cl^(+)`

In this mechanism, electrophile `Cl^(+)` attacks to electron rich benzene ring and replaces hydrogen. So, the reaction is electrophilic substitution reaction.
