Question

London forces are important only at_____

Answer 1

London-Dispersion force

• The intermolecular force of attraction describes the forces of attraction that keep molecules together.
• These forces are responsible for the liquids, solids, and solutions state of any compound.
• Some common types of intermolecular forces are London dispersion, dipole-dipole, Hydrogen bonding, and ion-ion force.
• The weakest intermolecular force is the London dispersion forces.
• In London’s dispersion forces there is the formation of temporary dipoles in a nonpolar molecule.
• These dipoles can be described as temporary attractive forces.
• The attractive force is inversely proportional to the sixth power of the distance between two interacting particles.
• These forces are always attractive.
• These forces are important only at short distances (~500 pm).
• The magnitude of these forces is determined by the particle’s polarizability.

Hence, the London forces are important only at short distances.
