New experimental data are reported for the thermodynamic investigation of the intermolecular halogenated compounds in nonpolar solvent. Experimental data are reported of excess molar volumes, excess Permittivity and excess Gibb’s free energy (DG) of binary mixtures of Flourobenzene, Chlorobenzne,Bromobenzne ,4Chlorobenzaldehyd and 4Florourobenzaldehyd in 1,4–dioxane at various concentrations at 298.2 K, 308.2 K and 318.2 K. The of mixing calculated using the experimental value of relative permittivity on the basis of Winkelmann–Quitzsch equatio
