Use the observation in the first column to answer the question in the second column. observation At 1 atm pressure, Substance E boils at 11. °C and Substance F boils at 30. °C. At 37 °C, Substance C has a vapor pressure of 89. torr and Substance D has a vapor pressure of 79. torr. The enthalpy of vaporization of Substance A is smaller than that of Substance B. question Which has a higher vapor pressure? Substance E Substance F Neither, E and F have the same vapor pressure.

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
