The excess molar volume VE { x(CH3OH or CH3CH2OH or CH3CH2CH2OH or CH3CH(OH)CH3 or CH3CH2CH2CH2OH or CH3CH(OH)CH2CH3 + water } have been calculated from measured values of density over the whole composition range at the temperature 298.15K and 308.15k in order to investigate OH….O specific interactions. The results are explained in term of the strong self association of the alkanols, the specific interaction between the alkanol and water and packing effects up on mixing. The experimental VE results presented here has been analyzed in term of the Graph theory which in turn deals with topology of the constituents of mixtures. It has been observed that VE values predicted by the graph theory compare well with their corresponding experimental values.
