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.

Published on Aug 27, 2013. A step-by-step explanation of how to draw the CH2Cl2 Lewis Dot Structure (Dichloromethane). Carbon (C) is the least electronegative atom and goes in the center of the CH2Cl2 Lewis structure. Hydrogen (H) atoms always go on the outside of a Lewis structure.
