ULTRASONIC STUDIES ON NON-AQUEOUS SOLUTIONS OF TOLUENE IN NITROBENZENE

Ultrasonic studies are extensively used in the conformational analysis of organic molecules. The ultrasonic study can give the indication of complex formation through hydrogen bonding in the system. Recently researchers suggested that adiabatic compressibility also used for detecting hydrogen bond formation in solutions. The ultrasonic velocity measurement is a unique tool in characterizing the structure and properties of the system and provides significant information on the arrangement of matter in solutions and also finds an extensive application in studying the nature of intermolecular forces. In the present work, attempts have been made to investigate the behavior of Toluene and Nitrobenzene at various concentrations also at different temperatures. The Ultrasonic velocity, viscosity and density are measured experimentally. In order to get more information on the nature and strength of molecular interaction, we have calculated the other related acoustical parameter such as adiabatic compressibility, intermolecular free length, Rao’s constant, internal pressure, and free volume. The non-linear variations of these derived acoustical parameters with different concentration of the solute explained on the basis of structural changes occurring in a solution.
