Hydrocarbon compound (CH4) in natural gas

Methane

Methane (US: METH-ayn, UK: MEE-thayn) is a chemical compound that has the chemical formula CH4 (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it is difficult because it is a gas at standard temperature and pressure.
