Question

Place the following substances in order of increasing boiling point. CH₃CH₂CH₂CH₂OH 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 van der Waals forces, so it has the lowest boiling point. Ethanol (CH3CH2OH) can form hydrogen bonds, giving it a higher boiling point than Ar but lower than dimethyl ether (CH3OCH3), which cannot form hydrogen bonds but has stronger van der Waals forces than Ar due to its larger electron cloud.
