Root Explanation

Acetonitrile is formed from "acetone" (from Latin *acetum*, meaning vinegar) and "nitrile" (from "nitrile" which refers to a compound containing the cyano group, derived from "nitro-" meaning relating to nitrogen). The word describes a compound that is derived from acetone and contains a nitrile group, indicating its chemical structure.

Memory Tip

Think of 'vinegar' ('acetum') as part of the base compound and remember that 'nitrile' indicates the presence of nitrogen in the structure, which helps you understand that acetonitrile is a compound related to acetone with a nitrogen component.
