Quizplus · Accepted Answer

Volatility is the tendency of a substance to vaporize. The more volatile a substance is, the easier it is for it to escape into the gas or vapor phase. In this case, pentane has the lowest boiling point and the weakest intermolecular forces, making it the most likely to vaporize and therefore the most volatile of the given molecules.
