(a) Describe the molecule xenon trioxide, XeO3, using four possible Lewis structures, one each with zero, one, two, or three Xe-O double bonds.
(b) Do any of these resonance structures satisfy the octet rule for every atom in the molecule?
(c) Do any of the four Lewis structures have multiple resonance structuers? If so, how many resonance structures do you find?
(d) Which of the Lewis structures in (a) yields the most favorable formal charges for the molecule? Explain.
Which of the following would be expected to be colored?
the structure they gave me already has two nonbonding electrons on Bromine with no formal charge
