WebFeb 15, 2024 · Phenols – Nomenclature, Preparation and Properties. Chemist. February 15, 2024. Phenols are hydroxyl derivatives of benzene in which –OH group is directly attached to benzene ring. Eg. If –OH group is attached to the side chain of an aromatic ring then it isn’t considered as phenol. This type of compounds are known as aromatic alcohol. Phenols are more acidic than typical alcohols. The acidity of the hydroxyl group in phenols is commonly intermediate between that of aliphatic alcohols and carboxylic acids (their pKa is usually between 10 and 12). Deprotonation of a phenol forms a corresponding negative phenolate ion or phenoxide ion, and the corresponding salts are called phenolates or phenoxides (aryloxides according …
