Statement 1 Bromobenzene, upon reaction with Br ₂ / Fe gives 1, 4-dibromobenzene as the major product. Statement 2 In bromobenzene, the inductive effect of the bromo group is more dominant than the mesomeric effect in directing the incoming electrophile.

Options

  1. AStatement 1 is true, Statement 2 is true, Statement 2 is a correct explanation for Statement 1.
  2. BStatement 1 is true, Statement 2 is true, Statement 2 is not a correct explanation for Statement 1.
  3. CStatement 1 is true, Statement 2 is false.
  4. DStatement 1 is false, Statement 2 is true

Correct answer

C. Statement 1 is true, Statement 2 is false.

Step-by-step solution

Bromine orientation is controlled by its mesomeric effect, its stabilisation of arenium ion by +M activity In bromobenzene, the inductive effect of the bromo group is more dominant than the mesomeric effect in the activity of ring.
