Refractive index of Isovaleric acid with Isopropyl myristate, Bromoform, and n-Butyl iodide have been measured at 298K, 303K, 308K, 313K and 318K over the whole mole fraction range were measured. The theoretical refractive index of binary mixtures was predicted using Gladstone-Dale, Heller, Newton and Eyring-John relations. The validity of these relations has been analyzed by comparing the experimental and theoretical refractive index. Comparison of various mixing rules has been expressed in terms of Root Mean Square deviation (RMSD).
