Comparative Study of Intermolecular Interactions of s-Triazine and Triazinothiocarbamides by Ultrasonic Interferometric Technique

S. S. Mishrikotkar and P. B. Raghuwanshi

The ultrasonic velocity and density measurement of s-triazine and triazinothiocarbamides were carried out in two different solvents, ethanol and dioxane, respectively for investigating solute-solvent interactions. The measurements of 0.01M solutions were carried out at 303.15 K. The aim of the study was to find the effect of protic/aprotic nature, polarity/non-polarity, dielectric constant, hydrogen bonding of solvent with resonance stabilization, structure, different substituents and their effect on ligands in solutesolvent interactions. The data obtained during the study were used for determining the most significant acoustic parameters like adiabatic compressibility (βs), apparent molar volume (Φv) and apparent motor compressibility (Φk). These parameters explore solute-solvent interactions in different solvents. In this investigation, the comparative study of effect of solvent and effect of substituents in the solute are studied on molecular interaction of matter.
