Every molecule or an atom exerts a force of attraction or
repulsion on the other constituents. This force is known as the
intermolecular force(IMFs). In other words IMFs are the various
forces of attraction that may exist between the atoms and molecules
of a substance due to electrostatic phenomena. These forces are
responsible for holding together of a substance.
These molecular forces originate from the attraction between
permanent dipoles (dipolar molecules) and are temperature
dependent. They occur whenever two particles come close to each
other.
The four prominent types are:
Strong ionic attraction. Recall lattice energy and its relations
to properties of solid. ...
Intermediate dipole-dipole forces. ...
Weak London dispersion forces or van der Waal's force These forces
alway operate in any substance. ...
Hydrogen bond. ...
Covalent bonding. ...
Metallic bonding.
