COMPARATIVE ANALYSIS BETWEEN SZEGED INDEX AND THE WIENER INDEX

Abstract

Topological indices are numerical quantities in graph theory that can be obtained from any type of graphical structure. The molecular structures of hexane, heptane, and the octane isomers are being converted into numbers with the use of topological indices. The physical characteristics of the structural isomers of the alkanes, hexane, heptane, and octane, are used to compute the distance-based topological indices of Wiener, Szeged, and mostar. The link between the three topological indices and the physical characteristics of the structural isomers of the alkanes is calculated in this article.  The correlation value between the distance-based topological indices and the physical parameters of melting point (Mp), surface tension (St), heats of vaporisation (Hv), boiling point (Bp), and molar volume (Mv) is here determined using the correlation approach.In this work, we calculate the relationship between the physical characteristics of the structural isomers of the alkanes and the distance-based topological indices. Additionally, we determine which indices are most useful in predicting the physical characteristics of the structural isomers of alkanes.
