A) \[{{O}_{2}}>O_{2}^{-}>O_{2}^{2-}\]
B) \[{{O}_{2}}>O_{2}^{-}<O_{2}^{2-}\]
C) \[{{O}_{2}}<O_{2}^{-}>O_{2}^{2-}\]
D) \[{{O}_{2}}<O_{2}^{-}<O_{2}^{2-}\]
Correct Answer: A
Solution :
Bond strength depends on bond order. More is bond order, more is the strength. Bond order of \[{{O}_{2}}=2\] Bond order of \[O_{2}^{-}=1.5\] Bond order of \[O_{2}^{2-}=1.0\] So order of relative bond strength, is\[{{O}_{2}}>O_{2}^{-}>O_{2}^{2-}\]
