Manipal MET2021ChemistryHaloalkanes and Haloarenes

A set of compound in which the reactivity of halogen atom in the ascending order is:

Options

  1. Achlorobenzene, vinyl chloride, chloroethane
  2. Bchloroethane, chlorobenzene, vinyl chloride
  3. Cvinylchloride, chlorobenzene, chloroethane
  4. Dvinylchloride; chloroethane, chlorobenzene.

Correct answer

A. chlorobenzene, vinyl chloride, chloroethane

Step-by-step solution

Stability of corresponding carbocation CH ₃ CH ₂ CH ₂= + C H C ₆ H ₅⁺ . So, the correct order of reactivity of halogen atom is chlorobenzene, vinyl chloride, chloroethane.
