Given the van der Waals a constant values for the following gases, which gas has the lowest boiling point?

Question

Quizplus · Accepted Answer

The van der Waals a constant is indicative of the strength of intermolecular forces, with a higher value suggesting stronger forces and thus a higher boiling point. Given this, the gas with the lowest a constant, which is option A, would have the weakest intermolecular forces and therefore the lowest boiling point.
