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.
Iodine is slightly soluble in water and gives a yellow solution. This element is shiny, blue-black, nonmetallic solid, volatizing into a violet-blue gas at room temperature. It has an irritating odor as well.he color of iodine solutions depends on the solvent and its polarity. Solutions are violet in color in hexane and other non-polar solvents and dark crimson in moderately polar ones. Solutions are brown or orange in strongly polar solvents, for example, ethanol and acetone.
