AlF3 - Aluminum Trifluoride:

First draw the Lewis dot structure:
AlF3 Lewis Structure
Electron geometry: trigonal planar. Hybridization: sp2

Then draw the 3D molecular structure using VSEPR rules:

The molecular geometry of AlF3 is trigonal planar with a symmetric charge distribution on the central atom.
Therefore this molecule is non-polar.
