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;).
