WebJan 25, 2024 · The phosgene (COCl2) molecule has an identical electron pair geometry and molecular geometry or shape i.e., trigonal planar. The three atoms bonded to the central carbon atom lie in a planar arrangement. There is no lone pair of electrons on the C-atom thus no distortion is witnessed in the geometry and shape of the molecule.
