Refractrometric studies on molecular interactions between some bromoalkanes and nonpolar hydrocarbons

Refractive indices of the twelve binary mixtures between polar aliphatic molecules, viz., 1-bromopropanc, 1-bromobutane, 1-bromopentane and nonpolar hydrocarbon molecules, viz., cyclohexane, benzene, 1, 4-dimethylbenzene and 1, 3, 5-trimethylbenzcne for the entire concentration range have been measured at 308.15 K. Deviation in refractive indices from that for ideal mixture, molar refraction, deviation in molar refraction from ideal mixture values, molecular radius and deviation in molecular radius from the values for ideal mixtures for these mixtures have also been evaluated. The results are discussed in terms of molecular interactions between the components of the binary mixtures.
