2. Brief Explanation
Butane, also called n-butane (normal butane), is an unbranched alkane with four carbon atoms in each molecule.
This organic molecule can be referred to two structural isomers, which is n-b utane and isobutane.
Butane reveals the form of gas at room temperature and atmospheric pressure.
The name of butane came from the roots but- (from butyric acid, named after the Greek word for butter) and –ane.
The IUPAC name of this organic molecule is Butane(normal or n-butane) and 2-methlypropane(Isobutane)

4. History
Butane was discovered by Dr. Walter O. Snelling in 1910, which is not that long ago.
While working for the U.S. Bureau of Mines in Pittsburgh, Pennsylvania, Dr. Snelling conducted research on evaporating gasoline. Throughout that process, he concluded that gasoline evaporated into propane, butane and other hydrocarbons.
Dr. Walter O. Snelling was a chemist who studied at Harvard, Yale, and George W ashington University. In addition to the discovery of propane and butane, he is credi ted for his contribution to the development of explosives and liquefied petroleum g as (butane blended with propane and other hydrocarbons).

5. How Butane is made
Butane comes from natural gas, which is colorless, odorless, and shap eless in its natural form. Extremely abundant in many parts of the wo rld, this type of gas is relatively inexpensive to mine and produce. It is a fossil fuel, created over the course of millions of years by a com plex process deep inside the earth from the remains of plants, anima ls, and numerous microorganisms.

6. Properties of Butane
At ordinary temperatures and pressures, n-butane is a colorles s gas. Its boiling point is −0.5 °C (272.6 K), and its melting poi nt is −138.4 °C (135.4 K). Likewise, i-butane, the structural iso mer of n-butane is a colorless gas, with a boiling point of °C (261 K) and a melting point of °C (114 K). Both is omeric forms can be readily liquefied at room temperature by compression.

7. Uses of butane in society
The butane is commonly used in cigarette lighters and portable cooking stoves. It is also used as refrigerant, replacing halomethanes. The butane is a high combustible material, but the butane, including in electrical goods is almost impossible to flame. In addition, the butane is also used as a heating fuel, a coolant, and a propellant in aerosols.

8. Problems associated with Butane
Inhalation of butane can cause euphoria, drowsiness, narcosis, asphyxia, and cardiac arrhythmia in blood pressure. In severe cases, the butane may result in death by asphyxiation and cardiac arrhythmia. If the butane is directly stained with throat of humans, it will cause laryngismus because the jet of fluid can cool rapidly by expansion.
