Question
Chapter 3, Problem 78P
Interpretation Introduction
Interpretation:
The molecule with the lowest boiling point needs to be determined.
Concept introduction:
The boiling point of a molecule depends on the type of intermolecular force of attraction. If the interaction forces are strong, the molecule will have a high boiling point and if the interaction forces are weak, the molecule will have a low boiling point. On comparing, molecules with covalent bonds have low boiling point than the molecules with ionic bonds because ionic bonds are stronger than covalent bonds.

Which compound or element has the lowest boiling point: Cl 2, KI, or LiF?
The molecular mass of butanol, C4H,OH, is 74.14; that
of ethylene glycol, CH2(OH)CH,OH, is 62.08, yet their
boiling points are 117.2 °C and 174 °C, respectively.
Explain the reason for the difference.
The two hydroxyl groups in ethylene glycol provide more
locations for the formation of hydrogen bonds. The
existence of more hydrogen bonds considerably
decreases the boiling point
O The two hydroxyl groups in ethylene glycol provide less
locations for the formation of hydrogen bonds. The
existence of less hydrogen bonds considerably increases
the boiling point

(a) Use the Clausius-Clapeyron equation and calculate the vapor pressure (mm Hg) of fluoroethane at
-80 °C, given that the vapor pressure is 400. mm Hg at a temperature of -46 °C. The enthalpy of vaporization of
fluoroethane is 23.0 kJ/mol.
(b) Calculate the enthalpy of vaporization for a compound if its vapor pressure is 70 mm Hg at -50 °C
and 323 mm Hg at -28 °C.
