Let the bond order of O22− be X and that of CO be Y. Then the value of XY is _____?
3
In this question, we have to check the bond order of each molecule.
→ To get the Bond order, we have to know the number of bonding electrons and number of anti-bonding electrons
→ To get number of bonding electrons and number of anti-bonding electrons. Let's draw MO energy level diagrams of the following species.
Now,
Bond Order =12[Number of Bonding electrons - Number of Anti Bonding electrons ]
⇒ O22− ⇒ BO = 12×[10−8] = 1 = (X)
CO ⇒BO = 12×[10−4] = 3 = (Y)
Therefore
X × Y = 1× 3 = 3
