Butane is an organic compoond wi the formula C4H10 that is an alkane wi fower carbon atoms. Butane is a gas at ruim temperatur an atmospheric pressur. The term mey refer tae either o twa structural isomers, n-butane or isobutane (or "methylpropane"), or tae a mixtur o these isomers. In the IUPAC nomenclatur, however, "butane" refers anly tae the n-butane isomer (which is the isomer wi the unbranched structur). Butanes are heichly flammable, colourless, easily liquefied gases. The name butane comes frae the ruits but- (frae butyric acid) an -ane.
