Methylidyne is a carbyne encountered in organic chemistry. Methylidyne has a linear doublet ground state and is thus paramagnetic. It is stable in the gaseous state. Methylidyne can be considered to be a monoradical; addition reactions are very fast and exothermic. Methylidyne tends to polymerise in high concentrations.
