Question = Is C2F2 polar or nonpolar ? Is C2Cl2 a bent molecule 2,005 results, page 8 chemistry. Answer: For XeO2, the shape is bent, but the overall geometry is tetrahedral when the lone pairs are considered; there is no way to place the lone pairs opposite one another, and therefore the 2 dipoles do not cancel out. Molecular Formula: C 2 Br 2: Synonyms: DIBROMOACETYLENE. 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.
