Butane

Butane is a hydrocarbon compound with the molecular formula C4H10. It belongs to the alkane family, which are saturated hydrocarbons characterized by single bonds between carbon atoms. Butane exists in two isomeric forms: n-butane and isobutane.

Physical Properties of Butane

• State: Butane is a colorless, odorless gas at room temperature and atmospheric pressure.
• Boiling Point: The boiling point of butane is approximately -1°C, which makes it suitable for use as a fuel in portable stoves and lighters.
• Flammability: Butane is highly flammable and is commonly used as a fuel in lighters and torches.

Chemical Properties of Butane

Butane undergoes combustion to produce carbon dioxide and water vapor. The balanced chemical equation for the combustion of butane is:

C4H10 + 6O2 → 4CO2 + 5H2O

Applications of Butane

Butane has several important applications, including:

• As a fuel for portable stoves, lighters, and torches
• In the production of synthetic rubber
• As a refrigerant in household and commercial refrigeration systems

Environmental Impact

Butane is a greenhouse gas and contributes to global warming. When released into the atmosphere, it can react with other pollutants to form ground-level ozone, which is harmful to human health and the environment.
