What will be the major product in the following mononitration reaction?

Correct answer

Step-by-step solution

Addition of NO 2 is an electrophilic addition. The N increases the electron density on the left benzene ring, whereas the carbonyl group decreases the charge density of the right benzene group. As a result, NO 2 is added to the left benzene group due to higher charge density.
