 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;).

(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
