Decreasing order of stability of \[{{O}_{2}},O_{2}^{-},O_{2}^{+}\] and \[O_{2}^{2-}\]is          [NEET 2015 (Re)]

A) \[O_{2}^{+}>{{O}_{2}}>O_{2}^{-}>O_{2}^{2-}\]

B)      \[O_{2}^{2-}>O_{2}^{-}>{{O}_{2}}>O_{2}^{+}\]

C) \[{{O}_{2}}>O_{2}^{+}>O_{2}^{2-}>O_{2}^{-}\]

D)      \[O_{2}^{-}>O_{2}^{2-}>O_{2}^{+}>{{O}_{2}}\]

Correct Answer: A

Solution :

Order of stability \[\propto \] bond order

\[\therefore \]Order of the stability of given specie

\[O_{2}^{+}>{{O}_{2}}>O_{2}^{-}>O_{2}^{2-}\]

Bond order .2.5 2 1.5 1
