Detailed Solution

The mesomeric action of bromine controls its orientation. Its +M action stabilises the arenium ion.

In bromobenzene, the bromo group's inductive impact predominates over the mesomeric effect, which makes the ring activity less activating than in benzene.

Statement 1 is true, but statement 2 is false.
