Question

Why ion dipole interactions are not considered as Van der Waal forces?? ​

Answer 1

♢♢♢♢♢Answer》》》》

=》Van der Waals forces form electrostatic bonds between molecules. Intermolecular bonds including Van der Waals bonds hold the molecules together in liquids and solids and are responsible for phenomena such as the surface tension in liquids and crystals in solids.

Answer 2

Answer...

Ion - dipole interaction comes into plane between and ion and a dipole molecule (like water) .

It is not considered as van der Wall forces because van der Wall force comes into play between uncharged molecule but here we have an ion which always has some charge.
