Methane is an organic compound with the chemical formula CH4. It is an alkane with one carbon atom. It is often found as the main part of natural gas. Methane is a greenhouse gas 23 times more effective than carbon dioxide. It is also less stable and slowly oxidates by oxygen to carbon dioxide and water.
Methane can be made by many chemical ways, but usually is found in natural gas and is obtained by fractional distillation, after it has become liquid.

"Methane is a retained name (see P-12.3) that is preferred to the systematic name ‘carbane’, a name never recommended to replace methane, but used to derive the names ‘carbene’ and ‘carbyne’ for the radicals H2C2• and HC3•, respectively.".
