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
