Let G be a simple connected graph having vertex set V and edge set E. The vertex-set and edge-set of G denoted by V(G) and E(G), respectively. The length of the smallest path between vertices u,v
V(G) is called the distance, d(u,v), between the vertices u,v. Mathematical chemistry is the area of research engaged in new application of mathematics in chemistry. In mathematics chemistry, we have many topological indices for any molecular graph, that they are invariant on the graph automorphism. In this research paper, we computing the Wiener index and the Hosoya polynomial of the Jahangir graphs J 5,m
for all integer number m ≥3. The Wiener index is the sum of distances between all pairs of vertices of G as W(G)=
And the Hosoya polynomial of G is H(G,x)=
, where d(u,v) denotes the distance between vertices u and v.
