Abstract

Constitutional isomers of alkanes with 6 through 9 carbon atoms are ordered differently by various topological indices. This fact allows the detection of similarity and dissimilarity between topological indices. The ordering induced by the average distance connectivity index J parallels the ordering induced by Wiener's index, but reduces the degeneracy of the latter index providing a much higher discriminating ability.
