Abstract: Induced dipole-induced dipole interactions have been studied in binary liquid mixtures of benzene, n-hexane, carbon tetra chloride and p-xylene with cyclohexane by ultrasonic velocity (U), density (ρ) and viscosity (η) measurements at 298K and at different mole fractions. Acoustical parameters such as adiabatic compressibility (β), free volume (Vf) internal pressure (i), intermolecular free length (Lf), available volume (νa), cohesive energy (CE) Rao constant (R) and molecular interaction parameter (U) were calculated from the experimental data. The ultrasonic investigations on four binary liquid systems reveal that in the liquid mixture containing non-polar liquids, there exist weak induced dipole-induced dipole attractions. The strength of this type of intermolecular attraction depends on the polarizability of molecules of the components present in the mixture.
