|Abstract:||The ultrasonic velocity, density and viscosity of the mixtures of the n–alkanols, namely, 1–propanol, 1–butanol, and 1–pentanol in toluene with nitrobenzene at 303 K have been measured. From the measured data of ultrasonic velocity, density and viscosity, some of the acoustical parameters such as adiabatic compressibility ( β), free length (Lf), free volume (Vf) and internal pressure ( πi) have been measured. The excess values of the above parameters are also evaluated. The results have been analysed and interpreted in terms of molecular interactions such as dipole-dipole interaction through hydrogen bonding between nitrobenzene and 1-alkanols, and donor-acceptor complexity observed between toluene and nitro-benzene molecules.|
