Phenolic acids, also known as phenol carboxylic acids, are aromatic acids that contain a phenolic ring and a carboxyl functional group. Flavonoids and phenolic acids constitute one of the most widespread groups of plant phenolics.
WebPhenol is no exception - the only difference is the slow reaction because phenol is such a weak acid. Phenol is warmed in a dry tube until it is molten, and a small piece of sodium added. There is some fizzing as hydrogen gas is given off. The mixture left in the tube will contain sodium phenoxide. Acidity of Substituted Phenols
WebJan 23, 2024 · You can recognise phenol because: It is fairly insoluble in water. It reacts with sodium hydroxide solution to give a colourless solution (and therefore must be acidic). It does not react with sodium carbonate or hydrogencarbonate solutions (and so must be only very weakly acidic). With metallic sodium fitbit githubWebPhenol does not give this test.
