Hexane is a chemical compound with empirical formula C6H14. The "hex" prefix thus refers to its six carbons, while the "ane" ending indicates that its carbons are connected by single bonds. Hexanes are largely unreactive, and are common ingredients in gasoline.
Hexane is an alkane (a type of hydrocarbon) with many possible isomers, each with different structural formulae.
There are also six-membered carbon rings, including cyclohexane (another alkane) and benzene.
Following is the structure of n-hexane:
Since it is an alkane, its presence can be told apart from alkenes since it does not discolour bromine water.
