BrF5 - Bromine Pentafluoride:
First draw the Lewis dot structure:
Electron geometry: octahedral. Hybridization: sp3d2
Then draw the 3D molecular structure using VSEPR rules:
The molecular geometry of BrF5 is square pyramidal with asymmetric charge distribution on the central atom.
Therefore this molecule is polar.
