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.
The elements that are gases at room temperature include hydrogen. They also include all the inert or noble gases, which are those elements in Group 18: helium, neon, argon, krâ¦ypton, xenon and radon. We also know that the halogens fluorine, chlorine and bromine are gases at room temperature (20Â°C). That leaves nitrogen and oxygen as the last of the elements that are gases at room temperature. All of these elements are nonmetals or halogens or inert gases. LAUGH OUT LOUD.
