The values of dielectric constant ( e ), refractive index (n) and density ( r ) of the binary mixtures of phenol and pchlorophenol with carbon tetrachloride, benzene and acetone have been measured experimentally at 301K. From these measurements evaluated the following parameter viz., polarization (P), molar refraction (R), molar volume (V), molar polarizability ( a ) also predict the following excess parameter like molar volume (VE), dielectric constant ( eE ), molar refraction (RE) and polarization (PE). The results are discussed in terms of molecular interactions.
