STUDY OF INTERMOLECULAR FORCES AND INTERACTIONS IN BINARY LIQUID MIXTURE CHLOROFORM, ACETONE, MXYLENE, AND CYCLOHEXANE IN DMSO

Thermodynamic studies like density ( ρ ), ultrasonic speed ( u ) and excess molar volume ( Vm E ) of binary liquid mixture of Chloroform ,Acetone, m- Xylene ,Cyclohexane+ DMSO have been carried out over the different range of composition at 308.15 K. Thermodynamic parameters like isentropic compressibility Ks , interaction parameter, χ12 , Flory parameters, coefficients, Ai and standard deviations, σ (Y E ) have been computed from experimental findings. The excess thermodynamic functions have been fitted to the RedlichKister polynomial equation. The experimental ultrasonic speeds have been analyzed in terms of Jacobson Free<br>Length Theory (FLT), Schaaff’s Collision Factor Theory (CFT), Nomoto’s relation, and Van Dael’s ideal<br>mixture relation. Intermolecular Free Length, Lf<br>, and available volume, Va , have been calculated from FLT,<br>CFT and thermo acoustic approach.
