While both resonance structures are chemically identical,the negative charge is on a different oxygen in each.This is important because neither resonance structure actually exists,instead there is a hybrid.The oxygens share the negative charge with each other,stabilizing it,and reducing the charge on either atom.Some results are removed in response to a notice of local law requirement.For more information,please see here.12345NextSynthesis of C40Symmetrical Fully - Chemistry EuropeSep 21,2011·Abstract In an effort to push olefin metathesis to the limits of conjugation in reactants and products,the C40-symmetrical carotenoids ,-carotene (1),lycopene (2),(3R,3R)-zeaxanthin (3),and
