Despite their - I effect, halogens are o- and p-directing in haloarenes. Explain.

Options

  1. AHalogens have lone pairs of electrons that participate in inductive effect and direct incoming groups to o- an
  2. BHalogens have a greater electron density, which makes them o- and p-directing.
  3. CHalogens attached to benzene rings exert – I and +R effect. +R effect dominates – I effect and increases the e
  4. DHalogens withdraw electron density from the benzene ring, leading to o- and p-directing effects.

Correct answer

C. Halogens attached to benzene rings exert – I and +R effect. +R effect dominates – I effect and increases the e

Step-by-step solution

Correct Option is : (C) Halogens attached to benzene rings exert – I and +R effect. +R effect dominates – I effect and increases the electron density at ortho and para positions of the benzene ring with respect to halogens
