BF3 - Boron Trifluoride:
First draw the Lewis dot structure:
Electron geometry: trigonal planar. Hybridization: sp2
Then draw the 3D molecular structure using VSEPR rules:
Click and drag the molecle to rotate it.
The molecular geometry of BF3 is trigonal planar with symmetric charge distribution on the central atom.
Therefore BF3 is nonpolar.
