Question

Explain various types of van der Waals forces giving the types of molecules in which

they are present.

Answer 1

dipole dipole forces
dipole induced dipole forces
induced dipole induced dipole forces or dispersion force or London force

Answer 2

The three types of van der Waals forces include:

1) dispersion force (weak)

2) dipole-dipole bonds (medium)

3) hydrogen bonds(strong).

Ion-dipole bonds are a special type of vander waals force in which ionic to covalent molecules are formed between ions and polar molecules.
