| 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. |
