Butane is an alkene and a hydrocarbon that is in the gaseous phase at room temperature and atmospheric pressure. [7][8], Rotation about the central C−C bond produces two different conformations (trans and gauche) for n-butane.[9]. [18] By spraying butane directly into the throat, the jet of fluid can cool rapidly to −20 °C (−4 °F) by expansion, causing prolonged laryngospasm. Very pure forms of butane, especially isobutane, can be used as refrigerants and have largely replaced the ozone-layer-depleting halomethanes, for instance in household refrigerators and freezers. The relative rates of the chlorination is partially explained by the differing bond dissociation energies, 425 and 411 kJ/mol for the two types of C-H bonds. Butane is an organic compound having the chemical formula C 4 H 10 and butene is an organic compound having the chemical formula C 4 H 8. The system operating pressure for butane is lower than for the halomethanes, such as R-12, so R-12 systems such as in automotive air conditioning systems, when converted to pure butane will not function optimally and therefore a mix of isobutane and propane is used to give cooling system performance comparable to R-12. In contrast to butane, this branched isomer features three CH3 groups and a CH group, all of these atoms adding up to the same C4H10 molecular formula.
