Solution
The correct option is D Isopropyl chloride Friedel craft reaction is carried out by the generation of a carbocation but in chlorobenzene, bromobenzene, chloroethene, lone pair of halogen are delocalized with π bonds to attain double bond character. Only isopropyl forms a relatively stable secondary carbocation, thus, it can be used as the halide component for Friedel-Crafts reaction.
