AsF5 - Arsenic 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 AsF5 is trigonal bipyramidal with symmetric charge distribution on the central atom.
Therefore this molecule is nonpolar.
