    The relative strength of interionic/ intermolecular forces in decreasing order is: [JEE MAIN Held on 07-01-2020 Morning]

    A) ion-ion > ion-dipole > dipole-dipole

    B) ion-dipole > dipole-dipole > ion-ion

    C) ion-dipole > ion-ion > dipole-dipole

    D) dipole-dipole > ion-dipole > ion-ion

    Correct Answer: A

    Solution :

    [a] Ionic interactions are stronger as compared to van der waal interactions. So, correct order is ion-ion > ion-dipole > dipole-dipole
