Abstract

Refractometric study of substituted 2-oxo-2-H-chromene-3-carbohydrazide derivatives is done in different binary mixture. Measurement of refractive index is done using Abbe’s refractometer. Molar refractions and polarizability constants are determined by using experimental data. The parameters obtained are used to determine molecular interaction between solutes and solvents.
