Phosphorus Pentachloride - PCl5 :

First determine the Lewis dot structure:
PCl5 Lewis Structure
Electron geometry: trigonal bipyramidal. Hybridization: sp3d

Next determine the 3D molecular geometry with VSPER rules:

The molecular geometry of PCl5 is trigonal bipyramid with symmetric electron region distribution around the central atom.
Therefore this molecule is nonpolar.
