Phenol bromine water test
WebPhenol is an aromatic compound in which the Hydroxy group(-OH) is attached to the Benzene ring. The test used to distinguish between them is the Bromine water test. Bromine dissolved in the water is called Bromine water. It is a reddish-brown-coloured solution. Web(d) Bromine Water Test: 1. Dissolve the given organic compound in glacial acetic acid. 2. Add bromine water solution to this dropwise. 3. If the colour of bromine disappears then it indicates the presence of phenol. (e) Phthalein Dye Test: 1. Take the organic compound to be tested in a test tube. 2. Add 200mg of phthalic anhydride to it. 3.
