Methylidyne, a carbon-based gas believed to have helped form the first molecules of life and one of the earliest molecules ever discovered among the stars, belongs to an unusual class of compounds called carbynes. These highly reactive compounds are not to be confused with the contentiously categorized, one-dimensional string of carbons of the same name or with the more familiar carbenes.

Carbynes, according to organic chemistry’s definition, are monovalent carbon species with three nonbonded electrons. . . .
