Question
Can someone please help me with these questions about the MO of CO2? Thanks. 9. The diagram shown is an MO scheme for CO2 a) If we create the CO2 anion, where does the negative charge primarily reside? ON THE CARBON ON THE OXYGEN(S 25, What will happen to the C-O bond strength if the molecule is ionized to a cation? Explain. b) artitals: c) Assuming that the Lewis diagram for CO2 indicates the appropriate number of bonds in the p orbitals molecule (4), do you judge the 4og MO in this diagram to be bonding, non-bonding, or anti- bonding? Explain. Ja, d) Neither CO2t nor CO2 are common ions. (Curious, eh??) What does this say about the absolute energies of the MO's in the diagram? Answer by referring to specific orbitals. co 2 0Explanation / Answer
a) If we to create a CO2- anion species, the negative charge primarily resides on the,
on the oxygen(s)
b) If a cation is formed of CO2, the bons strength of C-O would decrease. The octet rule would not be fulfilled for the atoms in the molecule and thus would have lower bond order for the C-O bond in the molecule and hence a reduction in bond strength.
c) In the given MO diagram, 4sigma(g) is bonding molecular orbital with lower energy than the non-bonding orbitals placed just in the middle of the MO diagram shown above.
d) With CO2 not forming either a CO2- or the CO2+ species, we can say that the energy levels of CO2 molecular orbitals are fixed and is very stable for the bonding molecular orbitals. The C-O bond order in the CO2 molecule is high and enables a stable molecular structure and geometry for CO2 species.
