WebCompounds like alcohols and phenol which contain an -OH group attached to a hydrocarbon are very weak acids. Alcohols are so weakly acidic that, for normal lab purposes, their acidity can be virtually ignored. However, phenol is sufficiently acidic for it to have recognisably acidic properties - even if it is still a very weak acid. WebPhenol (systematically known as hydroxybenzene) is an aromatic organic compound made up of the phenyl group (C6H5-) joined to a hydroxyl group (-OH). It contains an aromatic benzene ring and has the formula C 6 H 5 OH. Phenol has high melting and boiling points, is slightly soluble in water, and is weakly acidic.
