Values of dielectric constant (ε′) and dielectric loss (ε″) have been experimentally determined for binary liquid mixtures of acetonitrile with n-butyl alcohol at 10.75 GHz microwave frequencies at 20 degree centigrade and over the complete mole fraction range. The values of (ε′) and (ε″) have been used to evaluate the loss tangent ( ), molar polarization (P12), and a.c. conductivity ( ).The results are discussed in terms of intermolecular interactions. It has been shown that the results are positive over the whole range of composition. Viscosity, density and refractive index measurement of pure liquid and binary liquid mixtures were carried out at 20 degree centigrade. The values of viscosity have been used to evaluate the activation energy (Ea).These parameters have been used to explain the formation of hydrogen bonding and formation of complex in the binary liquid mixtures.
