Question

Bond order of O2, O2+, O2- and O22- is in order (A) O2- < O22- < O2 < O2+ (B) O22- < O2- < O2 < O2+ (C) O2+ < O2 < O2- < O22- (D) O2 < O2+ < O2- < O22-

Tardigrade Admin · Accepted Answer

Electrons Bond order O2 16 2.0 O2+ 15 2.5 O2- 17 1.5 O22- 18 1.0 Thus, BO is in order O22- < O2- < O2 < O2+

Q. Bond order of $O_{2}, O_{2}^{+}, O_{2}^{-}$ and $O_{2}^{2 -}$ is in order

$O_{2}^{-} < O_{2}^{2 -} < O_{2} < O_{2}^{+}$

$O_{2}^{2 -} < O_{2}^{-} < O_{2} < O_{2}^{+}$

$O_{2}^{+} < O_{2} < O_{2}^{-} < O_{2}^{2 -}$

$O_{2} < O_{2}^{+} < O_{2}^{-} < O_{2}^{2 -}$

Electrons Bond order

$O_{2}$ 16 2.0

$O_{2}^{+}$ 15 2.5

$O_{2}^{-}$ 17 1.5

$O_{2}^{2 -}$ 18 1.0

Thus, BO is in order
$O_{2}^{2 -} < O_{2}^{-} < O_{2} < O_{2}^{+}$

	Electrons	Bond order
$O_{2}$	16	2.0
$O_{2}^{+}$	15	2.5
$O_{2}^{-}$	17	1.5
$O_{2}^{2 -}$	18	1.0
