methane 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 : A one-carbon compound in which the carbon is attached by single bonds to four hydrogen atoms. It is a colourless, odourless, non-toxic but flammable gas (b.p. -161degreeC). | 2.02 | 1 | 0 | alkane; gas molecular entity; mononuclear parent hydride; one-carbon compound | bacterial metabolite; fossil fuel; greenhouse gas |
