    Topological index is a numeric parameter which describe some silent features (boil- ing point, stability and melting point, heat of formation and freezing point etc.) of a Molecular graph representing some chemical compounds. 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 degree based topological indices such as Randic index, Sum connectivity index, Harmonic index, First Zagreb, second zagreb and third zagreb in- dices, Augmented zagreb index, Hyper zagreb index, Atom bond connectivity index
