Abstract: Ultrasonic velocity (u), density () and co-efficient of viscosity () of pure and binary mixtures of diethyl ether with carbon tetrachloride, carbon disulphide and benzene have been measured at 303.15 K using an ultrasonic interferometer, pyknometer and Ostwald viscometer, respectively. Molecular interaction parameters i.e isentropic compressibility (s), intermolecular free length (Lf), molar volume (Vm), acoustic impedance (Z), available volume (Va), free volume (Vf), internal pressure (i) and the relaxation time () have been calculated and interpreted for the intra and intermolecular association among like and unlike molecules. Dipole-induced dipole type of interaction is found to be stronger in case of CCl4 mixture.
