PF5 - Phosphorus Pentafluoride:
First draw the Lewis dot structure:
Electron geometry: trigonal bipyramidal. Hybridization: sp3d
Then draw the 3D molecular structure using VSEPR rules:
The molecular geometry of PF5 is trigonal bipyramidal with symmetric charge distribution.
Therefore this molecule is nonpolar.
