These experimental data have been used to calculate excess volume V E , excess ultrasonic speeds u E , excess intermolecular free length L f E , excess acoustic impedance Z E , excess isentropic compressibility κ s E , deviation in viscosity Δη and excess Gibbs free energy of activation of viscous flow (G* E ). The values of L f E and κ s E are negative over the wide range of composition for all the binary mixtures, while the values of Z E are positive. These results have been used to discuss the nature of interaction between unlike molecules in terms of hydrogen bonding, dipole-dipole interaction, proton-acceptor interaction and dispersive forces. The viscosity data have been correlated using three equations: Grunberg and Nissan, Katti & Chaudhri and Hind et al. The excess/deviations were fitted by a Redlich-Kister equation and the results were analyzed in terms of specific interactions present in these mixtures.
