Abstract: Ultrasonic velocity and density have been measured in binary liquid mixture of N, N Dimethylacetamide (DMAc) with chloroform (CF) at 300K. Shape of the constituent molecules are considered as spherical, cubical, tetrahedral and six different discs with the application of scaled particle theory. To examine the intermolecular interactions in these liquid mixtures ultrasonic speeds are theoretically evaluated based on scaled particle theory. Theoretical velocities have been compared with observed velocities for each possible combinations. To examine the intermolecular interactions in these liquid mixtures, ultrasonic speeds are theoretically evaluated based on scaled particle theory. An attempt has been made to predict the behavioural shape of N, N Dimethylacetamide (DMAc) and chloroform (CF).
