Question
Product on monobromination of this compound is
The correct answer is:
It is electrophilic substitution, so electrophile must be attacked on o/p-position due to higher electron density on this position. In this ring, the attached –NH- group will have high electron density due to resonance and 
position is blocked, so electrophile is attached on 
position.
