Alkoxides

Part of speech: noun

Definitions

1. A group of chemical compounds that contain an alkoxy group, which is derived from an alcohol by removing the hydrogen atom of the hydroxyl group
2. Compounds formed by replacing the hydrogen atom of an alcohol's hydroxyl group with a metal, leading to distinct chemical properties
3. Substances that consist of an alkyl group bonded to an oxygen atom, influencing their reactivity in organic synthesis and catalysis

Etymology: Alkoxides are the plural of "alkoxide," and the word is built from two familiar pieces: "alkyl," the name for a group of carbon and hydrogen atoms such as methyl or ethyl, and "oxide," the name for a compound containing oxygen. Chemists combined these to name a compound in which an alkyl group is attached to an oxygen atom that carries a negative charge, which is what gives these substances their characteristic reactivity. The "-ide" ending in "oxide" and "alkoxide" comes from a standard chemical naming pattern, so the word is a technical coinage rather than something inherited from older English. Its meaning is fixed by the structure it names, not by any shift in everyday usage.
