Explanation:

Intermolecular forces

• Intermolecular forces are the attractive and repulsive forces that arise between the molecules of a substance.
• Intermolecular forces are mainly responsible for the physical characteristics of the substance.
• The stronger the noncovalent interactions between molecules, the more energy that is required, in the form of heat, to break them apart.
• The boiling point and melting point of a substance is proportional to the strength of its non-covalent intermolecular forces i.e. the stronger the intermolecular forces, the higher the boiling point and melting point.
• The strongest intermolecular force is the hydrogen bond.
• The weakest intermolecular forces are London dispersion forces.

London Forces:

• The instantaneous dipole–induced dipole attractions are called London dispersion forces.
• The name is given after Fritz London (1900–1954), a German physicist who developed this model to explain the intermolecular attractions that exist between non- polar molecules.
• London’s dispersion forces occur between all molecules.
• These very weak attractions occur because of the random motions of electrons on atoms within molecules.
