Abstract

Refractive index, molar refractivity and molar polarizability constant of substituted heterocyclic compound such as 5-ethoxy carbonyl-4- (4-nitro phenyl) -6-methyl-3, 4 dihydropyrimidine-2 (1H) 0ne, 5-ethoxy carbonyl-4- (4-bromo-phenyl) -6-methyl-3, 4 dihydropyrimidine-2 (1H) 0ne, have been studied in DMF, THF, Dioxan, Ethanol media at 303 K 0.1C temperature and different concentration (0.625x 10-3to 10.0x 10-3M). The values of molar refraction (Rm) and molar polarizability () constant are found to be decreasedwith decreasing concentration of solute in solvent. Viscosity coefficient (A, B) evaluate by using jone-dole equation. These parameters throw the light on the solute solvent interaction and solute solute interaction
