The ultrasonic velocity (V), density (ρ) and viscosity (η) measurements of Hydroquinone in n-propanol and iso-propanol have been carried out for the study of solute-solvent interaction. Experimental data have been used to calculate the isentropic compressibility (β_s), intermolecular free length (L_f), specific acoustic impedance (Z), molar sound velocity (R), relative association (R_A) solvation number (S_n) apparent molal adiabatic compressibility (ø_K), specific viscosity (η_sp), reduced viscosity (η) and relative viscosity (η_r). The sign and magnitude of these properties have been used to interpret the experimental results in terms of solute-solvent interaction.
