Question

explain the types of van der waals forces...

Answer 1

types of wandorwaal forces -

1.Dipole-dipole Forces

Dipole-dipole forces are weak, van der Waals forces that occur between polar molecules

2.Dispersion Forces

These forces arise when non-polar molecules become temporary dipoles. Since electrons are constantly in motion, there are times when the electron distribution of an atom is asymmetrical, so that it has a small charge.

 hope this helps u.......

Answer 2

The van der Waals constant 'a' represents the magnitude of intermolecular forces of attraction and the Van der Waals constant 'b' represents the effective size of the molecules.
