Which of the following has the highest boiling point?

Question

Quizplus · Accepted Answer

The boiling point of a compound increases with increasing molecular weight, but also with increasing strength of intermolecular forces. Among the given options, all have the same molecular weight, but the strength of the intermolecular forces increases in the order: CI < CBr < CCl < CF < CH. This is because the halogens (I, Br, Cl, F) have a greater electron density than carbon, making them more polarizable and therefore able to form stronger dipole-dipole interactions with neighboring molecules. Therefore, among the given options, the compound with the highest boiling point would be the one with the strongest intermolecular forces, which is CI₄.
