摘要: The present study exploring about the possible intermolecular interactions existing between ternary mixtures of 2-propanol + acetophenone substituted benzenes at varying temperatures. For this, densities, viscosities and speed sound for such as chlorobenzene, bromobenzene, nitrobenzene toluene with were measured a function mole fraction 303.15, 308.15 313.15K normal atmospheric pressure. binary solvent mixture prepared taken in ratio 1:3 on molefraction basis. added solutes different molar concentrations. From above observed experimental measurements, related excess parameters adiabatic compressibility (β E ), free length (Lf volume (Vf internal pressure (πi Gibb's energy (∆G viscosity (η ) interaction parameter (d) meticulously calculated. These values found to be positive well negative throughout whole range composition all four liquid systems are critically discussed light strong weak molecular unlike molecules.
