Rank the following compounds in order of increasing melting point,putting the compound with the least melting point first.

Question

Quizplus · Accepted Answer

Compound I is a nonpolar molecular compound with only London dispersion forces between its molecules. Compound II is an ionic compound with strong electrostatic forces between its ions. Compound III is a polar molecular compound with dipole-dipole interactions between its molecules. As the strength of intermolecular forces increases, so does the melting point. Therefore, I will have the lowest melting point, followed by II, and III will have the highest melting point. This matches the order given in choice C.
