## Discovery[edit | edit source]

Methane was first synthesized from carbon and hydrogen in 1904 by a Russian-American chemist, Vladimir Ipatiev (1867-1952).[1]

## Properties[edit | edit source]

Methane is the major component of natural gas, about 87% by volume. At room temperature and standard pressure, methane is a colorless, odorless gas;[2] the smell characteristic of natural gas as used in homes is an artificial safety measure caused by the addition of an odorant, often methanethiol]] or ethanethiol. Methane has a boiling point of −161 °C (−257.8 °F) at a pressure of one Atmosphere (unit)|atmosphere.[3] As a gas it is flammable only over a narrow range of concentrations (5–15%) in air. Liquid methane does not burn unless subjected to high pressure (normally 4–5 atmospheres).[4]
