Anisole is treated with in ethanoic acid (no catalyst). The major product is

  1. A2,4,6-tribromoanisole formed exclusively
  2. Bbromomethoxybenzene with Br on the methyl group,
  3. C3-bromoanisole
  4. D4-bromoanisole (1-bromo-4-methoxybenzene)

Answer: D

The methoxy group is a strong activating o/p director, so no Lewis acid is needed. Attack at the para position is favoured over ortho because of less steric hindrance, giving 1-bromo-4-methoxybenzene as the major product.
