Alkyls

Part of speech: noun

Definitions

1. A series of hydrocarbon radicals derived from alkanes by removing one hydrogen atom, typically used in organic chemistry for various reactions
2. Organic functional groups characterized by an alkane chain missing one hydrogen, often used in the production of surfactants and plastics
3. Hydrocarbon moieties formed from alkanes that lack a hydrogen atom, frequently involved in chemical synthesis and industrial applications

Etymology: "Alkyls" is the plural of "alkyl," a chemical term built from "alkane" and the suffix "-yl." Its story begins with "alcohol," itself a word with an unexpected Arabic origin. "Alkyl" was coined in the 1830s by the German chemist Justus von Liebig, who was working with the radical groups that persist unchanged through a chemical reaction. Liebig took the Greek-derived "-yl" from "hyle," meaning wood or matter, and attached it to "alk-" as shorthand for the alcohol series. The "-yl" suffix became a standard way to name these radicals, so "methyl" (from methylene, from methyl alcohol, "wood spirit") and "ethyl" followed the same pattern. "Alkyl" then became a general label for any such group derived from an alkane by removing one hydrogen atom.
