Which statements about anisole, $C X_{6} H X_{5} - O - CH X_{3}$ , are correct?

ABromine in ethanoic acid gives mainly 1-bromo-4-methoxybenzene
BIt does not react with sodium metal
CHot excess $HI$ gives phenol and $CH X_{3} I$
DIt gives a violet colour with neutral $FeCl X_{3}$

Answer: A, B, C

The methoxy group is ortho/para directing, with the para isomer major. Anisole has no O-H, so it does not react with Na. HI cleaves the

CH X_{3} - O

bond to give phenol and

CH X_{3} I

. The violet FeCl3 test needs a free phenolic OH, which anisole lacks.
