Explain Van-der-Waals force with example.

1.	Explain Van-der-Waals force with example.
Answer» It can be explain with 3 types. (a) Dipole and Dipole interaction : Dipole – Dipole interaction exists between polar molecules like NH₃, SO₂, HCl… Greater the dipole interaction greater is Vander Waal’s force. Hence such molecules liquefied easily. (b) Dipole & induced dipole interaction: A permanent dipole molecule can induce polarity in a non-polar molecular when comes near to each other. As a result between polar of non-polar molecule there exists force of attraction. (c) Induced dipole & Induced dipole interaction: Non polar molecules like, O₂ and N₂ having induced polarity on each other which is called Landon forces. When these two molecules comes near to each other the force increases.
