According to bond order concept the correct order of stability of

{O_2},\,\,\,O_2^ + ,\,\,\,O_2^ -

is _______

View answer and explanation

Correct option: B

O_2^ + > {O_2} > O_2^ -

Option B (

O_2^ + > {O_2} > O_2^ -

) is correct because the stability of a molecule is directly proportional to its bond order, and the bond orders are 2.5, 2, and 1.5 for

O_2^+

O_2

, and

O_2^-

respectively.
