Question

Using molecular orbital theory, compare the bond energy and magnetic character of O₂⁺ and O₂^– species.

Answer 1

(a) Compound (I) will form intramolecular hydrogen bond because NO₂ and OH group are close together in comparison to that in compound (II).

According to molecular orbital theory electronic configurations of O₂⁺ and O₂^– species are as follows :

Higher bond order of O₂⁺ shows that it is more stable than O₂^– .Both the species have unpaired electrons. So both are paramagnetic in nature.
