What Is the Boiling Point of Hexane?


Quick Answer

The boiling point of hexane is 69 degrees Celsius, or 156.2 degrees Fahrenheit. The boiling point for hexane, as with all longer hydrocarbon chains, is higher than that of molecules with smaller chains, such as those of methane and ethane.

Full Answer

The boiling point is the stage at which the kinetic energy of a compound's molecules becomes high enough that they can escape as a gas. In liquid form, the molecules of a compound interact through various intermolecular forces. In larger molecules, like those in longer hydrocarbon chains, these interactions are more plentiful and thus more energy is required to break free into a gaseous state. According to Elmhurst College's Virtual ChemBook, the boiling point of hexane falls within the mid-range of all saturated hydrocarbons.
