Question Detail
Question
Which of the following will have the lowest boiling point?
Correct Answer
Option B is the correct answer.
Detailed Explanation
CH4 (methane) has the lowest molecular weight and weakest intermolecular forces (only van der Waals), so it has the lowest boiling point. The chlorinated compounds have higher molecular weights and dipole-dipole interactions, increasing boiling points.
