CH4
Methane Meth"ane, n. [See {Methal}.] (Chem.) A light, colorless, gaseous, inflammable hydrocarbon, {CH4}; marsh gas. It is the simplest of the aliphatic hydrocarbons. See {Marsh gas}, under {Gas}. [1913 Webster]

{Methane series} (Chem.), a series of saturated hydrocarbons, of which methane is the first member and type, and (because of their general chemical inertness and indifference) called also the {paraffin (little affinity) series}. The lightest members are gases, as methane, ethane; intermediate members are liquids, as hexane, heptane, etc. (found in benzine, kerosene, etc.); while the highest members are white, waxy, or fatty solids, as paraffin proper. [1913 Webster]
