van der Waal’s force
van der Waal’s force is one of the weakest physical forces of nature which operates between non-bonded atoms and molecules. It arises due to the following three types of interactions-
(1) Dipole-Dipole interaction
(2) Dipole – Induced dipole interaction
(3) Induced dipole – Induced dipole interaction (London Dispersion)
(1) Dipole-Dipole Interactions
Dipole-dipole interactions operate between polar molecules (i.e. between the molecules possessing permanent dipole such as HCl, NH3, H2O, etc.). Here, the positively charged pole of one molecule attracts the negatively charged pole of another molecule.
