Which of the following chemical substances would you expect to have the lowest boiling point (you may consider molecular mass and the degree of intermolecular forces as primary controlling factors)?

Question

Quizplus · Accepted Answer

CH₄ has the lowest molecular mass and only exhibits London dispersion forces, which are the weakest intermolecular forces, leading to a low boiling point. The other choices have higher molecular masses and more complex structures, allowing for stronger intermolecular forces (dipole-dipole interactions and hydrogen bonding), leading to higher boiling points.
