Hexane (C6H14)
Hexane is an alkane of six carbon atoms, with the chemical formula C6H14.
The term may refer to any of the five structural isomers with that formula, or to a mixture of them. Hexanes are significant constituents of gasoline. They are all colorless liquids, odorless when pure, with boiling points between 50 and 70 °C (122 and 158 °F). They are widely used as cheap, relatively safe, largely unreactive, and easily evaporated non-polar solvents.
