text: Butane---\n\n\nButane, also called n-butane, is the unbranched alkane with four carbon atoms, CH3CH2CH2CH3. Butane is also used as a collective term for n-butane together with its only other isomer, isobutane (also called methylpropane), CH(CH3)3.\n\nButanes are highly flammable, colorless, easily liquefied gases. The name butane was derived by back-formation from the name of butyric acid.\n\n\nSTART FROM HERE\nIT WOULD BE BETTER----\n\nhttp://en.wikipedia.org/wiki/Butane\n\nHOPE THIS HELPS
