Which of the following pure substances would be expected to have the highest boiling point? A) CH₄ B) Cl₂ C) Kr D) CH₃Cl E) N₂

Question

Quizplus · Accepted Answer

D) CH₃Cl has the highest boiling point due to the presence of a polar covalent bond between chlorine and carbon. This leads to stronger intermolecular forces between the molecules, requiring more energy to break the bonds and thus a higher boiling point. Kr, on the other hand, is a noble gas with only weak London dispersion forces between its atoms, resulting in a very low boiling point. A, B, and E are organic compounds without polar functional groups, and thus have weaker intermolecular forces and lower boiling points compared to D.
