The Pivotal Role of Degree-Based and Neighborhood Degree-Sum-Based Topological Indices in Predicting the Physico-Chemical Properties of N-Octane Isomers

Abstract

Neighborhood degree-sum topological index is sum of the degree of neighborhood vertices of the vertex u and is denoted as S_u where degree-based topological index is the number of edges meet at u and is denoted as d_u. In this paper, we have done the comparative analysis between ten notable degree-based indices with their corresponding neighborhood degree-sum topological indices. We report here, the correlation of mentioned types of topological indices with five Physico-chemical properties of octane isomers. Furthermore, we have discussed a deeper-lying relation between Augmented Zagreb Index with Atom-bond Connectivity Index based on the correlation with one of the Physico-chemical properties (boiling point) of octane isomers.
