These indices characterize topology and are usually hold mathematical properties of Graph invariant. The process of transforming chemical information of chemical molecules into useful numerical results is known as molecular descriptor. These molecular descriptors are widely used in the study of Quantitative structure-activity relationships (QSARs) that provide insight into animate effects based on chemical structures. We’re going to investigate topological indices such as Randic Rλ ˜ (G), where λ is an actual number. Zagreb ˜ indices, Zagreb ˜ polynomials, Zagreb ˜ multi indices, Atom bond connectivity index (ABC), Geometric arithmetic index (GA), fourth edition of index (ABC), Harmonic index and fifth version of index (GA) for Bakelite network line graph.endepartment of mathematicsTopological Indices on Line Graphs of Chemical NetworkSadia Murtazatransforming chemical information of cheThesis
