WebMany monohydric phenols react rapidly with bromine water to yield solid bromination products. All the vacant ortho and para positions are usually substituted; typically, phenol … WebPhenol on treatment with chlorine or bromine water gives an immediate precipitate of 2,4,6−trihalogen derivative, when treated with bromine water it gives bromination of phenol. Phenol in aqueous medium is partially ionised and the phenoxide ion thus obtained is much more reactive than phenol itself towards electrophilic attack.
WebBromine water, often called the bromide bromate solution of bromine water, is a compound with the chemical formula Br2. Bromine water does have a density of 1.307 g/mL and a molar size of 159.81.
