Question

Arrange the following substances in order of increasing boiling point: CH₃OH, He, CH₃Cl, and N₂ A) CH₃OH < He < CH₃Cl < N₂ B) He < N₂ < CH₃OH < CH₃Cl C) N₂ < He < CH₃OH < CH₃Cl D) He < N₂ < CH₃Cl < CH₃OH E) CH₃Cl < He < N₂ < CH₃OH

Quizplus · Accepted Answer

Helium (He) is a noble gas with very low boiling point due to weak van der Waals forces. Nitrogen (N₂) is a diatomic molecule with a boiling point higher than He but lower than organic compounds due to its nonpolar nature. Chloromethane (CH₃Cl) has a higher boiling point due to dipole-dipole interactions. Methanol (CH₃OH) has the highest boiling point among these due to hydrogen bonding, which is stronger than the forces in the other substances.
