Next, draw the 3-dimensional structure for BrF5 using VSEPR rules. BrF5 or bromine pentafluoride is a polar molecule. In moist air, it will in fact release "smoke" containing hydrofluoric acid vapors coming from its reaction with the water in the air. As a result, there are no lone pairs of electrons, but bonding pairs of electrons also repel each other. The valence-shell electron-pair repulsion (VSEPR) model allows us to predict which of the possible structures is actually observed in most cases. Molecular Geometry: Molecular geometry is that kind of geometry that shows the three-dimensional representation of any given molecule. Br got 7electrons 5 of which are bond to 5 F , 2 Electrons=1 electrons pair. Chronic exposure may cause kidney damage and liver failure. Be sure to draw in the lone pair of electrons. tetrahedral. To determine the molecular geometry you have to determine the free electron pairs in the compound. Lone Pairs (around central atom) 1.
