The compound having the higher boiling point has to be identified. Concept Introduction: Boiling point: It is the temperature at which liquid converts to vapor. At boiling point the vapor pressure of liquid and the pressure of the surroundings are equal. The boiling point of a liquid increases as the intermolecular forces within the compound increases.

Question

Which type of intermolecular force accounts for each of these differences? (a) CH3OH boils at 65 °C; CH3SH boils at 6 °C. (b) Xe is a liquid at atmospheric pressure and 120 K, whereas Ar is a gas under the same conditions. (c) Kr, atomic weight 84 amu, boils at 120.9 K, whereas Cl2, molecular weight about 71 amu, boils at 238 K. (d) Acetone boils at 56 °C, whereas 2-methylpropane boils at -12 °C. CH3 CH3 O C CH3 CH3 CH3 CH Acetone 2-Methylpropane
