What are Inter-molecular forces?

What are the intermolecular forces? Explain in detail.

DEFINITION:

“The force of attraction present in the molecule of a compound is called intermolecular forces.”

CHARACTERISTICS OF INTERMOLECULAR FORCES:

1.       WEAK FORCES:

Usually these forces are very weaker than the bonding forces present with in these molecules.

2.       IN LIQUIDS AND GASES:

These forces are very weak among the molecules of gases and liquids.

3.       MELTING AND BOILING POINTS:

The melting and boiling points of liquids and solids depend upon the strength of these forces.

TYPES OF INTER MOLECULAR FORCES:

They are of three types:

·         Vander waal’s forces or London Dispersion Forces.

·         Dipole dipole forces.

·         Hydrogen Bonding
