Question

Rank the following compounds from lowest to highest boiling point. CH₃OH CH₄ H₂O C₂H₆ A) H₂O < CH₃OH < C₂H₆ < CH₄ B) C₂H₆ < CH₄ < CH₃OH < H₂O C) CH₄ < C₂H₆ < CH₃OH < H₂O D) CH₄ < C₂H₆ < H₂O < CH₃OH E) CH₄ < CH₃OH < C₂H₆ < H₂O

Quizplus · Accepted Answer

Methane (CH₄) and ethane (C₂H₆) are non-polar molecules with weak van der Waals forces, resulting in lower boiling points. Methanol (CH₃OH) and water (H₂O) can form hydrogen bonds, which are stronger, leading to higher boiling points. Water has the highest boiling point due to its ability to form more hydrogen bonds.
