Place the following substances in order of decreasing boiling point. H₂O F₂ CO A) CO H₂O F₂ B) F₂ CO H₂O C) H₂O CO F₂ D) CO F₂ H₂O E) F₂ H₂O CO

Question

Place the following substances in order of decreasing boiling point. H₂O F₂ CO A) CO > H₂O > F₂ B) F₂ > CO > H₂O C) H₂O > CO > F₂ D) CO > F₂ > H₂O E) F₂ > H₂O > CO

Quizplus · Accepted Answer

The order of boiling points is determined by the strength of intermolecular forces between molecules. H₂O has the highest boiling point because it can form strong hydrogen bonds between its molecules. CO has the next highest boiling point due to dipole-dipole interactions. F₂ has the lowest boiling point because it is a nonpolar molecule and only has weak London dispersion forces. Therefore, the correct order is H₂O > CO > F₂.
