Chemical and Physical Properties of Methane
The carbon atom central to the methane molecule has 4 valence electrons and thus needs 4 more electrons from four hydrogen atoms to complete its octet. The hydrogen atoms have a 109 degree bond angle giving the molecule a tetrahedral geometry .
A principal component of natural gas, methane is significant . Burning one molecule of methane in the presence of oxygen releases one molecule of CO2[carbon dioxide) and two molecules of H2O (water):
CH4 + 2O2 ---> CO2 + 2H2O
The strength of the carbon hydrogen covalent bond in the methane molecule is among the strongest in all hydrocarbons, and thus its use as a chemical feedstock is limited. The search for which one can facilitate C-H bond activation in methane and other low alkanes is an area of research with considerable industrial significance.
Pure methane is odorless, but when used as a fuel it is usually mixed with small quantities of strongly-smelling sulfur compounds such as ethyl mercaptan to enable the detection of leaks. Methane is a greenhouse gas with a global warming potential of 22 (meaning that it has 22 times the warming ability of carbon dioxide). Methane results from the decomposition of certain organic matters in the absence of oxygen. It is therefore also classified as a biogas.
