Ultrasonic investigations throw a light on the molecular interactions between solute and solvent molecules. The ultrasonic velocities, densities and viscosities have been measured for the binary liquid mixtures benzophenone and benzene of different mole fractions at 303.15 K. The obtained experimental data are used to calculate the acoustical parameters like adiabatic compressibility (β), free length (Lf), free volume (Vf), internal pressure (πi), interaction parameter (χ) and acoustic impedance (Z). The deviations in the parameters suggest the structure breaking tendency of the solvent molecules.
