1) Polar molecules should have opposite charge.

2) They should have some dipole moment value.

3) They should have electronegativity difference.

4) One the basis of solubility principle “like dissloves like" they should be soluble in polar molecules and insoluble or sparingly soluble in non-polar molecules.
