Abstract: Induced dipole-induced dipole interactions have been studied in binary liquid mixtures of benzene, <i style="">n</i>-hexane, carbon tetra chloride and <i style="">p</i>-xylene with cyclohexane by ultrasonic velocity (<i style="">U</i>), density (ρ) and viscosity (η) measurements at 298K and at different mole fractions. Acoustical parameters such as adiabatic compressibility (β), free volume (<i style="">V</i><sub>f</sub>) internal pressure (<img src='/image/spc_char/pi.gif' border=0><sub>i</sub>), intermolecular free length (<i style="">L</i><sub>f</sub>), available volume (<i style="">ν</i><sub>a</sub>), cohesive energy (CE) Rao constant (<i style="">R</i>) and molecular interaction parameter (<img src='/image/spc_char/lembda.gif' border=0><sub>U</sub>) 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.
