Abstract
Excess molar volumes V E, excess molar enthalpies H E, and speeds of sound u, data of {tetrahydropyran ( i) + benzene, or toluene, or o-, or p-, or m-xylene ( j)} binary mixtures have been measured as a function of composition at a temperature of 308.15 K. Speeds of sound data have been utilized to predict excess isentropic compressibilities, κ S E . V E, H E, and κ S E data for the investigated mixtures have been analyzed in terms of the Graph theory which in turn deals with topology of the constituents of mixtures. An analysis of V E data in terms of Graph theory suggests that these mixtures are characterized by interactions between dipole of tetrahydropyran and π-electron cloud of aromatic ring of aromatic hydrocarbons to form 1:1 molecular complex. It has been observed that V E, H E, and κ S E values predicted by the Graph theory compare well with their corresponding experimental values.
