PubChem Notes:

Methane The simplest saturated hydrocarbon. It is a colorless, flammable gas, slightly soluble in water. It is one of the chief constituents of natural gas and is formed in the decomposition of organic matter. (Grant & Hackh's Chemical Dictionary, 5th ed)

Methane - definition from

[(Science: chemistry) A light, colourless, gaseous, inflammable hydrocarbon, CH4; marsh gas. See marsh gas, under gas. (Science: chemistry) Methane series, 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.
