Identify the solvent used in bromination of phenol to obtain 2,4,6 – tribromophenol.
Answer: (B)
Solution
The group strongly activates the ring towards electrophilic substitution. In a polar solvent such as water, phenol ionises partly to the phenoxide ion, and bromine water (a polar medium) brings about substitution at all three activated positions (two ortho and one para), giving a white precipitate of
