Abstract

Viscosity (η) measurements were carried out for N-Benzothiazol-2-yl-3, 5-disubstituted pyrazolines viz. (BHPMPP), (BHPPP), (BHPCPP), (BHMPMPP), (BHMPPP), (BHMPCPP) in binary solvents at 295.15 K, 300.15 K and 305.15 K. With the help of above data molar volume (V_m), Enthalpy (ΔH), Entropy (ΔS) and Gibb’s energy (ΔG) of activation were calculated. The above study has been extended in determination of excess parameters. Results used to establish the intermolecular interaction between molecules.
