Etymology: The word is a plural, so the core history belongs to its singular, "organochlorine," which is a modern compound: "organo-" joined to "chlorine." The first part comes from the Greek "organon," meaning "tool" or "instrument," and in chemistry it marks compounds built around carbon. The second part is the element chlorine, whose name comes from the Ancient Greek "khlōrós," meaning "pale green" or "greenish yellow," a nod to the colour of the gas. Chemists named the element in 1811 after that colour, and the "-ine" ending on it follows the pattern of other halogen names. The compound's logic is simple: an organochlorine is any organic molecule in which chlorine is bonded to carbon. The term describes a chemical family rather than one substance, which is why the plural form is the one most often used.
