, a hydrocarbon that is obtained from natural gas or by refining petroleum. It can be liquefied at room temperature by compression. There are two structural isomersisomer
, in chemistry, one of two or more compounds having the same molecular formula but different structures (arrangements of atoms in the molecule). Isomerism is the occurrence of such compounds. Isomerism was first recognized by J. J. Berzelius in 1827.

 of butane. In normal butane, or n-butane, the four carbon atoms are joined in a continuous, unbranched chain; in isobutane, or 2-methylpropane, three of the carbon atoms are joined to the fourth by single bonds, resulting in a branched structure. The two isomers differ in certain of their chemical and physical properties, e.g., liquid n-butane has a higher boiling point (−0.6°C;) at atmospheric pressure than that of liquid isobutane (−10.2°C;).

butane

[′byü‚tān]
(organic chemistry)
C4H10 An alkane of which there are two isomers, n and isobutane; occurs in natural gas and is produced by cracking petroleum.

butane

a colourless flammable gaseous alkane that exists in two isomeric forms, both of which occur in natural gas. The stable isomer, n-butane, is used mainly in the manufacture of rubber and fuels (such as Calor Gas). Formula: C4H10
