Interpretation:
Reasons for which dipole-dipole forces are typically stronger than dispersion forces should be explained.
Concept Introduction:
Dipole-dipole forces are the forces of attraction that exist between the positive terminal of a polar molecule and the negative terminal of another polar molecule. For example: dipole-dipole forces exist in polar molecules like HF, HI, HCl etc.
Dispersion forces are very weak intermolecular attractive forces that exist between two atoms in a molecule, when their electrons are arranged in unsymmetrical manner to create temporary dipoles. For example: dispersion forces exist in halogen molecules like etc.
