Iodoethane

Part of speech: noun

Definitions

1. A colorless, volatile chemical compound consisting of an ethane molecule bonded to an iodine atom, used as an alkylating agent in organic synthesis and sometimes as a solvent
2. An organoiodine compound where a two-carbon alkyl group is attached to iodine, commonly utilized in laboratory settings for chemical reactions and preparation of other substances
3. A simple halogenated hydrocarbon formed by substituting one hydrogen atom in ethane with an iodine atom, employed in various chemical processes and experimental applications

Etymology: Iodoethane is a plain chemical coinage, built from two parts that each have their own history. The "iodo-" part comes from "iodine," named in 1814 for the violet vapour the element gives off when heated; the name draws on Ancient Greek "iodes," meaning violet-coloured, from "ion," the violet flower. The "ethane" part is the name of the two-carbon hydrocarbon, and its ending follows the pattern of "methane" and the other alkanes, with "-ane" from the Latin "-anus" that chemists borrowed as a regular suffix for saturated hydrocarbons. Put together, "iodoethane" names an ethane molecule in which one hydrogen has been replaced by an iodine atom. The "iodo-" prefix marks the substitution, the same way "chloro-" or "bromo-" marks the other halogens. The name is systematic rather than traditional, so it tells a chemist the structure directly from its parts.

Synonyms: ethyl iodide, haloalkane, alkyl iodide
