In this study, the binary mixtures n-butanol with formamide were investigated, focusing on their dielectric constant, density and refractive index. The dielectric constants were measured to assess the electrostatic interactions within the mixtures, density values provided insights into the overall composition and packing of molecules. Additionally refractive index data offered information on the optical properties of the mixtures, through systematic analysis. we observed variations in these properties in n-butanol with formamide binary mixtures. These findings contribute to a deeper understanding of the physicochemical behaviour of these mixtures. From the experimental dielectric data, excess dielectric constant, Kirkwood correlation factor, Bruggeman factor are estimated and reported in the study. The results show that the dielectric constants, densities and refractive index of the binary mixtures, decreases with increasing percentage of volume of n-butanol and the study shows the presence of molecular interactions and hydrogen bonding in the binary mixtures.
