The intermolecular force(s)responsible for the fact that CH₄ has the lowest boiling point in the set CH₄, SiH₄, GeH₄, SnH₄ is/are ________. A)hydrogen bonding B)dipole-dipole interactions C)London dispersion forces D)mainly hydrogen bonding but also dipole-dipole interactions E)mainly London-dispersion forces but also dipole-dipole interactions

Question

Quizplus · Accepted Answer

CH₄ has only London dispersion forces as its intermolecular force, whereas SiH₄, GeH₄, and SnH₄ have progressively higher atomic numbers and larger atomic sizes, resulting in stronger London dispersion forces. Therefore, they have higher boiling points than CH₄. Hydrogen bonding and dipole-dipole interactions are not present in these molecules.
