Dihydroxybenzenes

Part of speech: noun

Definitions

1. Organic compounds containing a benzene ring with two hydroxyl groups attached at different positions; these molecules often serve as intermediates in chemical syntheses and display distinctive chemical reactivity
2. Chemical substances characterized by a six-carbon aromatic ring bonded to two hydroxyl functional groups positioned variably, commonly involved in industrial applications and biological processes
3. Aromatic compounds featuring a hexagonal carbon structure with two hydroxyl substituents that influence their physical and chemical properties, making them important in various scientific and manufacturing contexts

Etymology: Dihydroxybenzene is a chemical name built like a formula: "di-" (two), "hydroxy-" (an OH group, from Greek "hydor", water, plus "oxy-", oxygen), and "benzene", the six-carbon ring whose name comes from gum benzoin, the resin it was first isolated from. Read literally, the name says "benzene with two hydroxyl groups attached." The plural "dihydroxybenzenes" simply refers to the family of such compounds. Because the two hydroxyl groups can sit at different positions on the ring, there are several distinct molecules, and the plural covers all of them. The three best-known members are catechol, resorcinol and hydroquinone, each distinguished by where those groups attach.

Synonyms: catechols, hydroquinones, resorcinols
