COMPARISON BETWEEN THE STRUCTURE BOILING-POINT RELATIONSHIPS WITH DIFFERENT DESCRIPTORS FOR CONDENSED BENZENOIDS

We compare the structure-boiling point models for benzenoid hydrocarbo ns based on three distance descriptors (the detour index, the Wiener s um index and its variant) and two connectivity indices (the vertex- an d edge-connectivity indices) with those based on the geometric distanc e indices. The conclusions of this study are that the best model is ba sed on the edge-connectivity index and that the models based on the ge ometric distance indices are good but not as good as models based on t he connectivity indices.
