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.
Gasoline is a mixture of hydrocarbons, including hexane. Gasoline and water do not mix because the nonpolar hydrocarbon molecules would disrupt the water in such a way as to produce a structure that was actually lower entropy; therefore, the mixture is less likely to exist than the separate liquids.hen you place a non-polar molecule in a polar solvent (like oil in water) the molecules try to minimize surface contact between them. (like you and a guy with a cold on an elevator). This is actually the basis for the cells in our bodies.
