Ethane is a saturated hydrocarbon in gaseous form. Ethane is the second most common alkane, followed by methane. It has two carbon atoms and six hydrogen atoms in it. In a lab environment, sodium propionate is used to produce it. Ethane is the most important gaseous fuel. Ethane and heavier hydrocarbons in natural gas can be easily isolated from the gas stream and liquefied under moderate pressure.
