Statement 1 Bromobenzene, upon reaction with $\mathrm{Br}_2 / \mathrm{Fe}$ 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.
  1. Statement 1 is true, Statement 2 is true, Statement 2 is a correct explanation for Statement 1.
  2. Statement 1 is true, Statement 2 is true, Statement 2 is not a correct explanation for Statement 1.
  3. Statement 1 is true, Statement 2 is false.
  4. Statement 1 is false, Statement 2 is true

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.
