| Abstract: | The induced dipole-dipole interactions have been
studied in binary liquid mixtures of pyridine, chlorobenzene, bromobenzene and
nitrobenzene with p-xylene by
measuring the ultrasonic velocity (U),
density (ρ) and viscosity (η) values at 298 K at various concentrations.
Acoustical parameters such as adiabatic compressibility (β), free volume (Vf), internal pressure ( i),
intermolecular free length (Lf),
absorption coefficient (α/f2),
relaxation time ( ), Rao constant (R),
cohesive energy (CE) and molecular interaction parameter with respect to
velocity ( U) 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. |
