The strongest intermolecular interaction in a, b, c are respectively ion-dipole interaction, hydrogen bond, dipole-induced dipole interaction.
(a) ion-dipole interaction is the strongest intermolecular interaction in CsCl in H2O.
(b) hydrogen bond is the strongest intermolecular interaction in CH3-CO-CH3 in H2O.
(c) dipole-induced dipole interaction is the strongest intermolecular interaction in CH3OH in CCl4.
(a) there is always a ion-dipole interaction between ion and polar molecules because here CsCl salt is dissociate into Cs+ and Cl- ions .and H2O is a polar molecule so here ion-dipole interaction .
(b) there is also a hydrogen bonding occurs between two polar solvents .here the electronegative O of acetone bonded with positive charge density of hydrogen in water .acetone is less polar and water is polar . so here hydrogen bonding occurs .
(c) here CH3OH is polar and CCl4 is non-polar . thus CH3OH induce a dipole in CCl4 which results in dipole -induced dipole interaction.
