Definition

ChEBI: Methane is 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. -161℃). It has a role as a fossil fuel, a member of greenhouse gas and a bacterial metabolite. It is a mononuclear parent hydride, a one-carbon compound, a gas molecular entity and an alkane. It is a conjugate acid of a methanide.
