Hexane vs. n-Hexane: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on March 3, 2024
Hexane is a hydrocarbon with six carbon atoms; n-hexane is the straight-chain isomer of hexane, specifically one of its several structural isomers.

Key Differences

Hexane refers to any of the isomers of a saturated hydrocarbon with the molecular formula C6H14. It includes a variety of structural forms, where the arrangement of carbon atoms can vary, leading to different physical and chemical properties. N-hexane, specifically, is the straight-chain isomer of hexane. It is one of the possible hexane isomers, characterized by a continuous chain of six carbon atoms with no branches. N-hexane is often highlighted for its role in industrial applications and its neurotoxic effects with prolonged exposure. It is used in laboratories, in the food industry, and as a cleaning agent.
Hexane in general can refer to any of its isomers, n-hexane is specifically known for its high degree of purity and specific arrangement, making it particularly useful in certain scientific and industrial applications. The distinction is important in contexts where the structural specifics of the compound affect its utility or effects, such as in solvent extraction processes where n-hexane's volatility and non-polarity make it ideal.
The term "hexane" when used without a prefix usually implies a mixture of isomers, not just the straight-chain n-hexane, but also includes other forms like iso-hexane which are used in various industrial solvents. This mixture has different properties, such as boiling points and solvent abilities, compared to pure n-hexane, affecting its suitability for certain applications.
Understanding the difference between hexane and n-hexane is crucial in chemistry and industry due to the distinct properties and applications of the different isomers. N-hexane's specificity is particularly significant in discussions about health and safety due to its neurotoxic potential, while general references to hexane might pertain to broader uses and a mixture of isomers with varied impacts and utilities.
