Abstract
The density, viscosity and ultrasonic velocity of N-phenyl-3-(pyridin-4-yl) prop-2-enamide in a solution of ethanol have been studied with different concentrations at 303, 308, and 313 K temperatures. Various acoustical parameters such as adiabatic compressibility (βad), intermolecular free length (Lf), relaxation time (t), free volume (Vf), internal pressure (Πi), acoustic impedance (Z), attenuation (a/f2), Rao’s constant (R), Wada’s constant, molar volume (Vm), cohesive energy (CE), of these solutions were computed from the experimental velocity, viscosity and density measurements. The variations of these properties with concentration provided the information about molecular interactions like effect of solute on the solute-solvent and solvent–solvent interactions. These parameters furnished the information about the nature of solute and its impact on the solvent structure.
