NEET Chemistry Substitution Reactions MCQ Question with Solution

What is the effect of resonance on the electron density in chlorobenzene at the ortho and para positions compared to the meta position?

A

Higher at ortho and para than meta

B

Higher at meta than ortho and para

C

Equal at ortho, meta, and para

D

Negligible at ortho and para

Option A

Resonance in chlorobenzene increases electron density at the ortho and para positions, making them more reactive compared to the meta position.
