In IUPAC nomenclature hexane is the unbranched isomer (n-hexane), the other four structures are named as methylated derivates of pentane and butane. Hexanes are significant constituents of gasoline. They are all colorless liquids at room temperature, odorless when pure, with boiling points between 50 Â°C and 70 Â°C. They are widely used as cheap, relative safe, largely unreactive and easily evaporated non-polar solvents. Hexane - dynamic viscosity over temperature.
We have a different situation when we try to mix hexane, C 6 H 14, and water. If we add hexane to water, the hexane will float on the top of the water with no apparent mixing. The reasons why hexane and water do not mix are complex, but the following gives you a glimpse at why hexane is insoluble in water.ut by trend, ionic and polar solutes are more soluble in polar solvents and non-polar molecules are soluble in non-polar (mostly organic) solvents. The units of concentration we just discussed are used to describe the degree to which a solute is soluble in a solvent.
