Question

Place the following substances in order of increasing boiling point. CH₃CH₂OH Ar CH₃OCH₃ A)Ar < CH₃OCH₃ < CH₃CH₂OH B)CH₃CH₂OH < Ar < CH₃OCH₃ C)CH₃CH₂OH < CH₃OCH₃< Ar D)CH₃OCH₃ < Ar < CH₃CH₂OH E)Ar < CH₃CH₂OH < CH₃OCH₃

Quizplus · Accepted Answer

Argon (Ar) is a noble gas with very weak dispersion forces, resulting in the lowest boiling point. Dimethyl ether (CH₃OCH₃) has dipole-dipole interactions, leading to a higher boiling point than argon. Ethanol (CH₃CH₂OH) can form hydrogen bonds, resulting in the highest boiling point among the three substances.
