Question

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

• A. ion-dipole $>$ dipole-dipole $>$ ion-ion
• B. dipole-dipole $>$ ion-dipole $>$ ion-ion
• C. ion-ion $>$ ion-dipole $>$ dipole-dipole
• D. ion-dipole $>$ ion-ion $>$ dipole-dipole

Answer 1

Answer: (C)

Interionic/intermolecular forces $ \propto $ 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
