The pairwise intercorrelation between 12 topological indices is studied in benzenoid hydrocarbons with up to six rings. The functions used in the intercorrelations were linear, quadratic, cubic, power low, and logarithmic relationships. The last two relationships failed to intercorrelate the selected topological indices. The results obtained suggested that there are basically three subclasses of independent topological indices in the benzenoids studied. When contrasted with the previous findings in alkanes, our results suggest that the cyclicity leads to the stronger intercorrelation of topological indices than the branching of a molecule. © 1992 John Wiley & Sons, Inc.
