Molecular interaction studies using ultrasonic technique in the binary liquid mixtures of cyclohexanone with o-cresol and p-cresol have been carried out at 303 K. Using the measured values of ultrasonic velocity, density and viscosity, acoustical parameters and their excess values are evaluated. From the properties of these excess parameters the nature and strength of the interactions in these binary systems are discussed.
