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