Quick Summary

The methide ion (CH-3) is the simplest carbanion, meaning it's an organic compound with a negative charge primarily on a carbon atom. It's derived from methane (CH4) by losing a proton (H+).1

Methide can also refer to a binary compound of methyl with a metal, such as mercuric methide (Hg(CH3)2). Additionally, it can be an intermediate in resin formation from phenol and formaldehyde, known as a quinone methide.2

Carbanions are important as chemical intermediates in creating other substances, including plastics. The methide ion has a pyramidal structure, similar to ammonia.1
