The VSEPR model also fails to predict the structure of certain compounds because it does not take relative sizes of the substituents and stereochemically inactive lone pairs into account. As a result,...The VSEPR model also fails to predict the structure of certain compounds because it does not take relative sizes of the substituents and stereochemically inactive lone pairs into account. As a result, VSEPR does not give correct geometries for these transitional metal complex compounds.. For example, [SeCl 6 ] 2- , [TeCl 6 ] 2- ,and [BrF 6 ] - are predicted to adopt pentagonal bipyramidal geometries according to VSEPR since the central atom can have seven electron pairs.
