benzenediol

Benzenediols or dihydroxybenzenes are aromatic chemical compounds and polyphenols in which two hydroxyl groups are substituted onto a benzene ring. Because they have at least one hydroxyl group covalently bonded directly to a carbon atom in a benzene ring, they are in a class of organic compounds called phenols. There are three isomers of bezenediol, each of which has its particular name as shown in the mini-table below. Various other ways of naming these three chemical compounds are also shown: Similar to other phenols, the hydroxyl groups on the aromatic ring of a benzenediol are weakly acidic. Each benzenediol can lose an H+ from one of the hydroxyls to form a type of phenolate ion. Hydroquinone can lose an H+ from both to form a diphenolate ion. The disodium diphenolate salt of hydroquinone is used as an alternating comonomer unit in the production of the polymer PEEK.
