By defining a polyhaloalkyl and a polyhaloalcohol, using recurrence method, the generating functions for counting staggered conformations of polyhaloalkyls and polyhaloalcohols have been obtained. The numerical results in Table 1－3 are given. 　　According to the results obtained, using graphtheoretical method, the generating functions for counting staggered conformations of polyhaloalkanes have been devived. Some numerical results are given in Table 4. 　　Furthermore, the staggered conformations of polyhaloalkanes according to their symmetry groups have been classified and the generating function of counting the staggered conformations belong to each group have been derived. The numerical results are given in Table 5.
