All of the compounds below have approximately the same molecular mass.Predict which compound has the lowest boiling point.

Question

Quizplus · Accepted Answer

Compound A, CH₃-CH₂-CH₂-CH₃ (butane), has the lowest boiling point because it is a nonpolar molecule and only experiences weak van der Waals forces, whereas the other compounds can form hydrogen bonds (B and C) or have dipole-dipole interactions (D and E), which require more energy to overcome.
