Abstract: The induced dipole-dipole interactions have been studied in binary liquid mixtures of pyridine, chlorobenzene, bromobenzene and nitrobenzene with <i style="">p</i>-xylene by measuring the ultrasonic velocity (<i style="">U</i>), density (ρ) and viscosity (η) values at 298 K at various concentrations. Acoustical parameters such as adiabatic compressibility (β), free volume (<i style="">V</i><sub>f</sub>), internal pressure (<img src='/image/spc_char/pi.gif' border=0><sub>i</sub>), intermolecular free length (<i style="">L</i><sub>f</sub>), absorption coefficient (α/<i style="">f</i><sup>2</sup>), relaxation time (<img src='/image/spc_char/tow.gif' border=0>), Rao constant (<i style="">R</i>), cohesive energy (CE) and molecular interaction parameter with respect to velocity (<img src='/image/spc_char/lembda.gif' border=0><sub>U</sub>) have also been calculated. The acoustical parameters can be used to assess the strength of induced dipole-dipole interactions in the four systems studied. The strength of dipole-induced dipole attractions correlates with dielectric constant and dipole moment of the polar compounds.
