The products formed in the reaction of phenol with Br ₂ dissolved in CS ₂ at 0^ C are

Options

  1. Ao -bromo, m -bromo and p -bromophenols
  2. Bo-bromo and p -bromophenols
  3. C2,4,6-tribromo and 2,3,6-tribromophenols
  4. D2,4-dibromo and 2,6-dibromophenols

Correct answer

B. o-bromo and p -bromophenols

Step-by-step solution

Phenol when treated with Br ₂ in the presence of non-polar solvent CS ₂ , it gives only o- and p -bromophenols instead the trisubstituted products. Reason for the above observation is supression of phenoxide ion in non-polar solvent. Thus, we get only mono substituted products.
