| Abstract: | In this paper we find out the compute formula of the number of isomer of such a kind of cyclanes having one link and a straight branch by means of the generating function. Let a denote the number of carbon atom, then the above number is given by n- 3 ( n>4 ) . And, these covalent molecules are realized with the aid of the unordered partition in two parts. In addi -tion, we also discuss some problems of the valence boud structure of formula
