| Abstract: | The Randid index of an chemical molecule whose molecular graph is G is the sum of the weights （dG （u）dG （v））^- 2/1 of all edges ut, of G, where dG （u） denotes the degree of the vertex u of the molecular graph G. In this paper, we character some properties of chemical trees with k pendant vertices and maximal Randic index. |
