Web15 hours ago · CH2Cl2 Lewis Structure. The Lewis theory of chemical bonding—although quite primitive and the most limited theory on electronic structure—does help one to determine how valence electrons are arranged around the constituent atoms in a molecule. The purpose of this theory is to help visualize the chemical bonding of atoms in molecules. WebAnswer (1 of 2): If you by dichloromethylene are meaning CCl2 (and not CH2Cl2, which should more correctly be designated as dichloromethane), then dichloromethylene is synonymous with dichlorocarbene.
