Butane vs. Isobutane: What's the Difference?

Edited by Sara Rehman || By Sumera Saeed || Published on December 21, 2023
Butane is a straight-chain alkane with four carbon atoms, while isobutane is a branched-chain isomer of butane.

Key Differences

Butane (C₄H₁₀) is an alkane with a linear structure of four carbon atoms linked consecutively. Isobutane, however, also known as methylpropane, is a structural isomer of butane with a branched chain, where one carbon atom is connected to three others at the central point.

Butane is used as a fuel in lighters and portable stoves due to its easy liquefaction under pressure. While, isobutane, because of its lower boiling point compared to butane, is often used as a refrigerant and in aerosol propellants.

In butane, the molecular structure is straight, which influences its boiling and melting points. Whereas, isobutane's branched structure results in different physical properties, such as a lower boiling point, making it more suitable for certain applications.
