Some new chalcones of 2-Furaldehyde have been synthesized and their characterization was done by IR, 1H NMR, and mass spectral data. Ultrasonic velocities of various solutions of different concentrations of these synthesized compounds in dimethyl formamide and chloroform have been measured at 308.15 K by using single crystal interferometer at a frequency of 2 MHz. The density and viscosity have also been measured by pycnometer and Ubbelhode viscometer. Using these experimental data, various acoustical parameters are calculated, which are interpreted in terms of solute-solute and solute-solvent interactions in different solutions.
