Abstract :Abstract Density and speed of sound were measured earlier by us for binary liquid mixtures formed by Benzonitrile, Chlorobenzene, Benzyl chloride and Benzyl alcohol with Benzene at temperature range 298.15 to 313.15 K and atmospheric pressure over the whole concentration range. Pseudo-Gruneisen parameter and internal pressure were derived from the measured values of density and ultrasonic velocity. These values were compared with the theoretical values obtained by the utilization of Flory theory, Ramaswamy and Anbananthan model and model suggested by Glinski to predict the behavior of weakly interacting liquids. The observed properties derived from measured data were fitted to Redlich-Kister polynomial relation to estimate the binary coefficients and standard errors. Excess Pseudo-Gruneisen parameter for these binary mixtures was computed to study the molecular interactions involved in the liquid systems.
