Excess volumes (V-E), ultrasonic sound velocities (u), and viscosities (eta) have been measured for the binary mixtures of acetophenone with o-chlorotoluene, m-chlorotoluene, p-chlorotoluene, o-nitrotoluene, and m-nitrotoluene at 303.15 K. Excess volumes are positive over the entire composition range in all the binary mixtures. Furthermore, from the experimental sound velocity data isentropic compressibility (K-S) and deviation in isentropic compressibility (Delta K-S) from ideal behavior was also computed at the same temperature, and these values are negative in all the binary mixtures. The viscosity data are analyzed on the basis of corresponding states approach. Deviation in viscosities are positive over the entire composition range. The measured data are explained on the basis of intermolecular interactions between unlike molecules.
