Butane Formula

Butane Formula

Butane belongs to the alkane group, and it is highly inflammable. It exists in the gaseous state at room temperature and atmospheric pressure. It can be easily liquefied and stored to be used as a fuel. It is used as a fuel gas all over the world. The Butane Formula is C4H10.

What is Butane?

It is classified into hydrocarbons. Butane Formula is represented by C4H10. Butane belongs to the family of paraffinic hydrocarbons and is a colourless, odourless gaseous hydrocarbon (compound of carbon and hydrogen). They have the chemical formula C4H10. Normal butane, also known as n-butane, is a compound in which the carbon atoms are connected in a straight chain. Isobutane, on the other hand, has a branched chain. Both substances are found in natural gas and crude oil and are produced in significant amounts when petroleum is refined to make gasoline. The topic titled as Butane Formula can be easily understood with the help of the study resources provided by Extramarks.

Butane Chemical Formula

Butane Formula is C4H10. By absorbing the butanes in natural gas in a light oil, it is possible to isolate them from the significant amounts of lower-boiling gaseous elements like methane and ethane. The butanes so obtained can either be fractionally distilled to separate them from the propane and then from each other, or they can be stripped from the absorbent together with the propane and sold as liquefied petroleum gas (LPG).

Butane Structural Formula

It is important to know the Butane Formula. It is given by C4H10. Furthermore, it consists of four carbons. The structure of butane shows that it is a straight chain alkane. In order to give the unburned gas an unpleasant smell that may be easily noticed by the human nose, it is sometimes combined with small amounts of mercaptans as fuel. This makes it simple to spot butane leaks. While hazardous substances like hydrogen sulphide and mercaptans are present, their concentrations are so low that suffocation and fire hazards posed by butane take precedence over their toxicity.


Butane is a colourless gas with the density equal to 2.48 g/mL. It is highly reactive in nature therefore it is used in large numbers of reactions. Butane is soluble in water and in other solvents. It is also an odourless gas. Butane Formula is given by C4H10. All the topics covered in the chemistry chapters need to be revised in order to score well. The Extramarks learning platform has learning modules available in different media that students can make use of according to their own convenience.


The representation of Butane Formula is C4H10. Butane is used as a fuel gas. It can also be used in the gasoline industry for blending purposes. The primary ingredient utilised to control the Reid vapour pressure while combining gasoline is n-butane (RVP). Refineries increase the RVP by adding additional butane to the fuel, since starting engines with winter fuels requires a considerably greater vapour pressure. The research octane number (RON) and motor octane number (MON) of n-butane, which are 93 and 92, respectively, are both relatively high. Butane can also be used in the manufacture of several chemical compounds, including butadiene, as well as the extraction of fragrances at low temperatures. Butane is used in the chemical industry to create synthetic rubber, as well as other materials like plastic and sprays.
