1- Ion-dipole forces are generated between polar water molecules and a sodium ion. The oxygen atom in the water molecule has a slight negative charge and is attracted to the positive sodium ion.
2- These intermolecular ion-dipole forces are much weaker than covalent or ionic bonds.
its not considered as van der waals force as van der waals force will come into concept when the molecules will be uncharged , but in this case 1 of the molecule will be slightly -ve charge as mentioned earlier .
