IF5 - Iodine Pentafluoride:

First draw the Lewis dot structure:
IF5 Lewis Structure
Electron geometry: octahedral. Hybridization: sp3d2

Then draw the 3D molecular structure using VSEPR rules:
Click and drag the molecle to rotate it.

The molecular geometry of IF5 is square pyramidal with asymmetric charge distribution on the central atom.
Therefore IF5 is polar.
