Which of the following can be used as the halide component for Friedel – Crafts reaction?

  1. A
    Isopropyl chloride
  2. B
    Chlorobenzene
  3. C
    Bromobenzene
  4. D
    Chloroethene

Solution & Step-by-step Explanation

In Friedel-Crafts alkylation/acylation, the carbon-halogen bond must be easily broken to form a carbocation or a polarized complex.In vinyl halides (Chloroethene) and aryl halides (Chlorobenzene, Bromobenzene), the lone pair on halogen is in resonance with the system, giving the bond a partial double bond character. This makes it very difficult to break.Isopropyl chloride () is an alkyl halide that can easily form a secondary carbocation.
