Title: how to determine where a 3rd substituent added to substituted benzene?
Post by: AussieKenDoll on August 11, 2020, 12:31:02 PM

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.
