What product is formed when Phenol is treated with excess Bromine water at room temperature?
Answer and explanation
Correct answer: C. 2,4,6-Tribromophenol
- Step 1: The -OH group is a strongly activating ortho/para-director that activates the benzene ring toward electrophilic attack. Step 2. In polar aqueous medium, phenol ionizes into phenoxide, which undergoes rapid electrophilic substitution at all activated positions, forming a white precipitate of 2,4,6-tribromophenol. Answer: 2,4,6-Tribromophenol (white precipitate). Why not the others: o-Bromophenol or p-Bromophenol are obtained using non-polar solvents like CS2; Bromobenzene lacks hydroxyl group.
