Question
Assuming roughly equivalent molecular weights, which of the following would have the highest boiling point?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Quaternary ammonium salts are ionic compounds with strong ionic bonds, giving them the highest boiling points. They are solids at room temperature, unlike the other compounds which are liquids or gases.
Hint
Which compound is ionic and has the strongest intermolecular forces?
