NEET2024ChemistryHaloalkanes and HaloarenesActual

The following reaction method is not suitable for the preparation of the corresponding haloarene products, due to high reactivity of halogen, when X is :

Options

  1. AF
  2. BI
  3. CCl
  4. DBr

Correct answer

A. F

Step-by-step solution

- Aryl chlorides and bromides can easily be prepared by electrophilic substitution of arenes (toluene) with Cl ₂ and Br ₂ respectively in the presence of Lewis acid catalyst ( Fe in dark). - Reaction with I ₂ is reversible and requires the presence of oxidising agent. - Corresponding fluoroarene is not prepared by this method due to high reactivity of fluorine. Hence, ' X ' is F .
