Draw the 3D molecular structure using VSEPR rules, The molecular geometry of BrF5 is square pyramidal with asymmetric charge distribution on the central atom.
Bromine has 35 electrons in atomic structure he can share his 5 electron with fluorine n makes BrF5 fluorine has 7 electrone in his outer orbital so he can share 1 electrone with bromine n complete his orbital by taking 1 electron from bromine but bromine is more powerful than fluorine so he can not gain his electron but he shares so bromine shares his 5 electron with 5 fluorine n makes a structure of square pyramidal it is because of the dis-attraction of fluorine ion it makes a angel of 90° so it can be situated in a form of square pyramidal form. Thus it is a structure of square pyramidal in BrF5 with 90° each angel.
