Question

Compare relative stability of O2+ and O2- using bond order?

Answer 1

Know this bond order gives stability of a molecule. If fractional b.o. exists its unstable unless its because of resonance in the molecule. O2- has b.o. of 1.5 and O2+ has b.o. 2.5 both are fractional thereby both are unstable and existence is hard but yeah, comparitively as O2+ has higher b.o. it should be more stable.
