Nov 19, 2016 · O=CCl2, otherwise known as the early chemical warfare agent Phosgene is SP2 hybridized about the carbon atom, thus it is "trigonal planer" in molecular geometry terms. Here's a ball & stick model with oxygen (red) double bonded to the carbon atom. molecular geometry is tetrahedral (e.g. CH 4). If there is one lone pair of electrons and three bond pairs the resulting molecular geometry is trigonal pyramidal (e.g. NH 3). If there are two bond pairs and two lone pairs of electrons the molecular geometry is angular or bent (e.g. H 2O).
