Which has the maximum entropy of vaporisation?

The entropy of vaporization is then equal to the heat of vaporization divided by the boiling point(BP), and According to Trouton's rule, the entropy of vaporization (at standard pressure) most of the liquids has similar values.The entropy of vaporization is a state when there is an increase in entropy as liquid changes into a vapour. This is due to an increase in molecular movement which creates a randomness of motion.The entropy of vaporization is equal to the enthalpy of vaporization divided by boiling point. It can be represented as∆Svap = ∆HvapTB/P
