Dihydroxybenzene

Part of speech: noun

Definitions

1. An organic compound characterized by the presence of two hydroxyl groups attached to a benzene ring, often used in chemical syntheses and analytical applications
2. A type of aromatic compound that contains two hydroxyl (-OH) functional groups on its benzene structure, significant in various chemical reactions
3. A dihydro derivative of benzene, possessing two hydroxyl groups, which plays a role in industrial processes and in the production of dyes and pharmaceuticals

Etymology: Dihydroxybenzene is a systematic chemical name, built to describe a molecule rather than to tell a story. It is formed from "di-", meaning two, "hydroxy-", referring to the hydroxyl group (an oxygen atom bonded to a hydrogen, OH), and "benzene", the six-carbon ring that gives aromatic compounds their name. Together the name says that benzene carries two hydroxyl groups attached to its ring. The "benzene" element itself traces back to gum benzoin, a resin whose name passed through Latin and Arabic before chemists applied it to the ring compound. "Hydroxy-" is a nineteenth-century chemists' combining form, so the whole word is a modern technical coinage, not an ancient one. Because the two hydroxyl groups can sit at three different positions on the ring, the same chemical name pattern covers three isomers: catechol (1,2), resorcinol (1,3), and hydroquinone (1,4). "Dihydroxybenzene" is the general term that names all three, and each has its own common name.

Synonyms: catechol, hydroquinone, resorcinol
