The relative strength of the interionic/ intermolecular forces in a decreasing order is:

The relative strength of the interionic/ intermolecular forces in a decreasing order is:
  1. dipole-dipole > ion-dipole > ion-ion
  2. ion-dipole > ion-ion > dipole-dipole
  3. ion-dipole > dipole-dipole > ion-ion
  4. ion-ion > ion-dipole > dipole-dipole

Solution

Interionic/intermolecular forces ∝ charge present on species
As ions are charged while dipole is only partially charged so the relative strength of interionic/intermolecular forces in decreasing order is:
Ion-Ion > Ion-Dipole > Dipole-Dipole
