BrF₅ - Bromine Pentafluoride:

First draw the Lewis dot structure:

Electron geometry: octahedral. Hybridization: sp³d²

Then draw the 3D molecular structure using VSEPR rules:


Decision:
The molecular geometry of BrF₅ is square pyramidal with asymmetric charge distribution on the central atom.
Therefore this molecule is polar.
