Please answer the question with an explanation.
Four liquids are described in the table below. Use the second column of the table to explain the order of their freezing points, and the third column to explain the order of their boiling points. For example, select '1' in the second column next to the liquid with the lowest freezing point. Select '2' in the second column next to the liquid with the next higher freezing point, and so on. In the third column, select '1' next to the liquid with the lowest boiling point, '2' next to the liquid with the next higher boiling point, and so on.

Millikan oil drop experiment
List the substances BaCl₂, H₂, CO, HF, and Ne in order of increasing normal boiling point. Solution (a) BaCl₂-IONIC substance: strongest intermolecular force. High normal b.p. H₂ - Has ONLY LDF intermolecular forces. Its MM = 2.016 g/mol. CO - Has BOTH LDF and dipole-dipole interactions, thus dipolar forces are more predominant. HF - Has BOTH LDF and H-Bonding. Will have quite a high normal b.p. Ne - Has ONLY LDF available. Its AM = 20.180 g/mol. Thus: BaCl₂ has the highest comparative b.p. since it is ionic. When a substance has LDF only, then it is necessary to compare other factors, principally MM, AM, and/or shape. For these small molecules, mass will suffice. Lowest normal b.p. Highest normal b.p. H₂ < Ne HF < BaCl, IDF only (MM decides) < dipole-dipole < H-bond
