In this study, 1-(2,4-dichlorophenyl)-3-(napthalen-1-yl)-2-propen-1-one was synthesized and characterised by FT-IR and 1HNMR. The various concentrations (ranging from 0.01M to 0.1 M) of its solutions in DMF were prepared. Density, viscosity and ultrasonic velocity measurements of pure solvent and solutions were carried out at DMF at 288.15 K, 293.15 K, 298.15 K and 303.15 K. These measured data were used to determine thermodynamic parameters such as isentropic compressibility (β), intermolecular free pathlength (Lf), acoustic impedance (Z), Relaxation Strength (r), Molar compressibility (W), Apparent molar volume (ɸV), Apparent molar compressibility (ɸβ), Solvation number (Sn), Free Volume (Vf), Internal Pressure (π) and Gibbs free energy (∆G). Using these experimental data, various acoustical parameters have been calculated, which were interpreted in terms of solute-solute and solute-solvent interactions in solutions.
