Concept explainers
(a)
Interpretation:
The liquid that is expected to have greater enthalpy of vaporization has to be given.
Concept Introduction:
Intermolecular forces: Intermolecular forces are electrostatic in nature and include van der Waals forces and hydrogen bonds. Molecules in liquids are held to other molecules by intermolecular interactions, which are weaker than the intramolecular interactions that hold the atoms together within molecules and polyatomic ions. The three major types of intermolecular interactions are,
- Dipole-dipole interactions
- London dispersion forces
- Hydrogen bonds

(d)
Answer to Problem 11.56QE
The enthalpy of vaporization is expected to be greater for
Explanation of Solution
The intermolecular force present in ammonia is hydrogen bonding and the intermolecular force present in phosphine is dipole-dipole attraction/London dispersion force. The enthalpy of vaporization of liquid depends on its boiling point. The boiling point of ammonia is said to be greater. Stronger the intermolecular force, higher the boiling point, greater will be the enthalpy of vaporization. Therefore, the enthalpy of vaporization of ammonia would greater than phosphine.
