Step-by-step solution
The benzene ring to which >NH group is directly attached is activated for the attack of B r + as –NH group is highly ringh activating due to +R effect. the ring to which ƒ ‚ C = O group is directly attached is deactivated towards electrophillic substitution. As ƒ ‚ C = O group is ring deactivating due to –R effect in addition the ƒ ‚ N H group is ortho-para directing but para position is favourable for the attach of B r + . Hence the product formed is as follows
