Let us understand the types of given intermolecular forces

a) dipole-dipole : this is present between two polar molecules having permanent dipole

eXample : dipole dipole interaction between HCl-HCl molecule

b) dipole induced dipole : here a polar molecule having a dipole induces dipole in another non polar molecule due to attraction /repulsion for electrons and attraction / repulsion for nucleus.

c) hydrogen bond : the interaction between a hydrogen atom bonded with a highly electr-onegative element (F,O or N) and another highly electro-negative element (F,O or N)

Example Water-water

d) london dispersion : these are weekest of all the intermcolecular forces and are between the electrons of one molecule / atom and nucleus of another molecules.

The strongest intermolecular forces is hydrogen bond
