Question

Quizplus · Accepted Answer

The molecules in the set are all covalent compounds and do not contain hydrogen atoms bonded to electronegative atoms, so hydrogen bonding is not possible. The only intermolecular force that is present in these molecules is London dispersion forces, which increase with the size and polarizability of the molecule. The molecule with the lowest boiling point, CH₄, is the smallest and least polarizable of the set, so it experiences the weakest London dispersion forces and has the lowest boiling point.
