BCl3 - Boron Trichloride:
First draw the Lewis dot structure:
Electron geometry: trigonal planar. Hybridization: sp2
Then draw the 3D molecular structure using VSEPR rules:
The molecular geometry of BCl3 is trigonal planar with symmetric charge distribution around the central atom.
Therefore this molecule is nonpolar.
