Quick Summary

Methylidyne, also known as methenyl or methine, is a chemical compound represented by the formula HC≡ or =CH−. It is a trivalent radical derived from methane. A radical in chemistry is a molecule with at least one unpaired electron, making it highly reactive. The methyl group (CH₃) is a common structural unit in organic compounds, consisting of a carbon atom bonded to three hydrogen atoms. While methylidyne itself is a transient intermediate in chemical reactions, the methyl group is a stable component of many molecules.1234
