WebJun 18, 2015 · I understand that we need to add F e B r X 3 while brominating benzene in order to polarize the bromine molecule. However, we do not need to add such a Lewis Acid in the case of phenol, because it is activated by the − O H group, and so polarizes the bromine molecule on its own. The sample is dissolved in water, or a mixture of water and ethanol, and a few drops of neutral ferric chloride (FeCl3) solution, which is prepared by adding de-ionised water. Add sodium hydroxide to the mixture until a permanent brown precipitate is formed. The formation of a red, blue, green, or purple coloration indicates the presence of phenols. Where the sample is insoluble in water, it may be dissolved in dichloromethane with a small amount of pyridine.
