Sample Problem

Arrange the following attractive forces in order of increasing strength:

Solution

London dispersion forces, dipole-dipole attraction, and hydrogen bond are intermolecular forces. Covalent bond, metallic bond and ionic bond are intramolecular forces. Intramolecular forces are stronger than intermolecular forces. Thus, the correct order is: London dispersion forces, dipole-dipole attraction, hydrogen bond, covalent bond, metallic bond, ionic bond.
