(Wikipedia, L'Encylopédie Libre, <a href=\"https://fr.wikipedia.org/wiki/Radical_hydroxyle\" target=\"_blank\">https://fr.wikipedia.org/wiki/Radical_hydroxyle</a>)"@fr, "The monovalent functional group –OH found, for example, in alcohols and phenols. It consists of a hydrogen atom and a oxygen atom bound together by a covalent bond. In alcohols, the hydroxyl group is attached to a carbon atom in a hydrocarbon chain, while in phenols the hydroxyl group is attached directly to the hydrocarbon ring. It should not be confused with the hydroxide ion, OH–.
