Which of the following substances would you expect to have the lowest boiling point? A) sodium nitrate, NaNO₃ B) copper C) methane, CH₄ D) glycerine, C₃H₅(OH)₃ E) diamond

Question

Quizplus · Accepted Answer

Methane is a non-polar molecule with only weak van der Waals forces between its molecules. Therefore, it requires the least amount of energy to break these forces and reach its boiling point, which is -161.5°C. The other options have stronger intermolecular forces, which require more energy to overcome and reach their respective boiling points.
