What exactly is an ion-dipole interaction and can you give an example?

This are interactions between ions that are charged and a molecule/s that has a dipole.

Dipoles usually result from a great charge difference between the two ions. One would be partially negative and the other positive, one of the examples from the top of my head would be water I think. You can read more about it in the textbook, for me in the 6th edition it was around page 92.

Ion-dipole forces can be 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. These intermolecular ion-dipole forces are much weaker than covalent or ionic bonds.
