PCl3 - Phosphorus Trichloride:
First draw the Lewis dot structure:
Electron geometry: tetrahedral. Hybridization: sp3
Then draw the 3D molecular structure using VSEPR rules:
Click and drag the molecle to rotate it.
The molecular geometry of PCl3 is trigonal pyramidal with asymmetric charge distribution on the central atom.
Therefore this molecule is polar.
