Abstract: Refractive index ,molar refractivities and molar polarizability constant of 3-ethyl-4-methyl-N-[2-[4-[(4- methylcyclohexyl)carbamoylsulfamoyl]ethyl]-5-ethyl-3-methyl-2-oxo-1H-pyrrol-1-yl]benzamide in 20% Methanol media at 303.15 K ± 0.10C temperature and different concentrations ( 0.625x10-3 to10.0x 10-3M ).The values of molar refraction (Rm) and molar polarizability (α) constant are found to be decreased with decreasing concentration of solute in solvent. Viscosity coefficient (A, B) evaluate by using john–dole equation. These parameters throw the light on the solute-solvent interaction and solute-solute interaction.

Keywords: molar polarizability constant, Molar refractivities and Viscosity coefficient.
