Phosphorus Pentachloride - PCl5 :
First determine the Lewis dot 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.
