Abstract	The excess molar heat capacities, $$ \left( {C_{{P}}^{\text{E}} } \right)_{12} $$ , of binary mixtures of o-chlorotoluene (1) with pyridine, α-, β- or γ-picoline, benzene, toluene or o-xylene (2) have been measured as a function of composition at 298.15, 303.15 and 308.15 K using a micro differential scanning calorimeter (Model-μDSC 7 Evo). The $$ \left( {C_{{P}}^{\text{E}} } \right)_{12} $$ data have been fitted with the Redlich–Kister equation to calculate binary adjustable parameters along with standard deviations. The sign and magnitude of values of o-chlorotoluene (1) + pyridine or α- or β-picoline (2) are dictated by the relative proportion of components in the mixtures. However $$ \left( {C_{{P}}^{\text{E}} } \right)_{12} $$ values for o-chlorotoluene (1) + γ-picoline (2) mixture are positive and $$ \left( {C_{{P}}^{\text{E}} } \right)_{12} $$ values for o-chlorotoluene (1) + benzene or toluene or o-xylene (2) mixtures are negative over the entire mole fraction range. The topology of the constituent molecules has been employed (Graph theory) to determine the $$ \left( {C_{{P}}^{\text{E}} } \right)_{12} $$ data of the studied mixtures. It has been observed that $$ \left( {C_{{P}}^{\text{E}} } \right)_{12} $$ values obtained by Graph theory are in agreement with the experimental values.
