Which of the following statements are correct?

  1. AIn nitrobenzene, the meta position has the highest electron density among the ring carbons.
  2. BIn anisole, the +M effect of increases the electron density at the meta position.
  3. CIn chlorobenzene, the -I effect of Cl outweighs its +M effect, so the ring is deactivated.
  4. DIn phenol, the +M effect of outweighs its -I effect at the ortho and para positions.

Answer: A, C, D

In phenol the +M effect makes the ortho and para positions rich in electrons. In chlorobenzene the ring is deactivated overall because -I dominates. In nitrobenzene the -M effect depletes the ortho and para positions, so meta is relatively the richest. In anisole, +M does not place charge at the meta position (the negative charge appears only at ortho and para).
