The simplest hydrocarbon , methane is a gas with a chemical formula of CH4. 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 .
Methane is an odorless, colorless flammable gas. It is used primarily as fuel to make heat and light. It is also used to manufacture organic chemicals.Methane can be formed by the decay of natural materials and is common in landfills, marshes, septic systems and sewers.ethane can also be found in coal gas. Pockets of methane exist naturally underground. In homes, methane may be used to fuel a water heater, stove and clothes dryer. Methane evaporates quickly.
