ABSTRACT
Densities, speed of sound and dynamic viscosity of liquid mixtures of 2-Chloroaniline with carboxylic acids (ethanoic acid, propanoic acid and butanoic acid) have been calculated over the entire composition range and at T = (303.15–318.15) K. Changes in the physical properties have been studied as a function of temperature and alkyl chain length of carboxylic acids. By using density, speed of sound, viscosity data the excess molar volume (), excess isentropic compressibility (
), excess Gibbs energy of activation flow (
) of liquid mixtures have been calculated. In addition, excess partial molar volume,

excess partial isentropic compressibility,

and excess partial molar volume,

at infinite dilution over the whole composition range have also been calculated. Further the topology of electron density obtained by non-covalent interaction plots are used to identify the evolution of strong and weak interactions between dimers of binary liquid mixtures.
