There is a Toluene which has a -NHCOCH3 on the para position and if we react it with Br2 , FeCl3 to give a Br substituent ,where does this Br added to?
Does it added to the ortho position next to Methyl group? Or generally how it determined?

No catalyst is needed. Practically one isomer is formed.

The substituents are in competition - the more activating one wins.
