Ultrasonic velocity and density measurement of 2-hydroxy-3-substituted-5-methyl-bromoqcetophenones and 2-(4'-H/chloro)benzylidene-5-methyl-7-substituted coumaran-3-ones were carried out in ethanol and dioxane respectively for solute-solvent, solute-solute interactions. These interactions were also performed with Cu(II) and Fe(III) metal ions at 303.15 K. The data obtained during the study is used for determining the most significant acoustic parameters like apparent molar compressibility (ΦK) and specific acoustic impedance (Z). These parameters explore solute-solute and solute-solvent interactions in different solvents. In this investigation, the comparative study of effect of solvents, effect of metal ions and effect of substituents in the solute are studied on molecular interaction of the matter.Keywords

Ultrasonic velocity, density, viscosity have been measured experimentally for the solution of leaf extract of Ocimum Tenuiflorum in 50% ethanol with various concentrations at 298.15 K, 303.15 K, 308.15 K keeping constant frequency of 4 MHz. As the acoustical parameters like adiabatic compressibility, intermolecular free length, relative association, relaxation time, specific acoustic impedence would prove to be more useful to predict and confirm the molecular interactions, these have been determined by measuring the Ultrasonic Velocity, density, viscosity of the prepared solution. A variation in these parameters will provide a strong information regarding the molecular interactions taking place in the solution.Keywords
