Lewis electron structures give no information about molecular geometry, the arrangement of bonded atoms in a molecule or polyatomic ion, which is crucial to understanding the chemistry of a molecule. Explain why the bond angles in some real molecules do not match the bond angle predicted by VSEPR theory – for example, H2O, SO2 , ClF3 , NH3 , SF4 , BrF5 . CO2 Molecular Geometry. Once we know how many valence electrons there are in BrF5 we can distribute them around the central atom with the goal of filling the outer shells of each atom. [3], Bromine pentafluoride reacts violently with water, but it will form bromic acid and hydrofluoric acid (especially when moderated by dilution with acetonitrile), simple hydrolysis products:[4]. The electron geometry of BrF5 in its Lewis structure is octahedral, and the hybridization is sp3d2. Chronic exposure may cause kidney damage and liver failure. tetrahedral.
