Which of the following molecules will have the highest boiling point?

Question

Quizplus · Accepted Answer

The molecule with the highest boiling point will have the strongest intermolecular forces, which are caused by dipole-dipole interactions and/or hydrogen bonding. Option C has a high boiling point because it is a highly polar molecule with six fluorine atoms attached to the benzene ring, which increases the polarity and the strength of the dipole-dipole interactions. The other options either have weaker dipole-dipole interactions, no hydrogen bonding, or are not polar enough to form strong intermolecular forces.
