Abstract This paper bring to light an interesting phenomenon:if hybridization of valence orbital of central atom A is sp3d and there is lone electron pair in the orbital for polyatomic molecules ABn, the lone electron pair always occupies an equatorial position; and if there is polybond between A and B in the molecule, B always occupies an equatorial position. It inquired into the internal cause of the phenomenon and demonstrated the rule by inductive method.
