Question

{"1":{"data":" Bromobenzene, upon reaction with $B{r}_2/Fe$ gives
\r\n1,4-dibromobenzene as the major product.
","imageType":"-1","image":"-1"},"2":{"data":"In bromobenzene, the inductive effect of the
\r\nbromo group is more dominant than the mesomeric effect in
\r\ndirecting the incoming electrophile.
","imageType":"-1","image":"-1"}}

Answer 1

Bromo group is deactivating due to dominance of inductive
effect over resonance effect. However, orientation is determined
by mesomeric effet of -Br.
