About the Ediz Eccentric connectivity index of Linear Polycene parallelogram Benzenoid
A graph G=(V,E) consists of a set of vertices V(G) and a set of edges E(G) In chemical graphs, the vertices and edges of the graph correspond to the atoms of the molecule and chemical bonds, respectively. For a graph G=(V, E) the Eccentric Connectivity indexx (G) is equal to x(G) v vVG dv e I a
