Question

The order of relative bond strength of oxygen molecule, superoxide ion and peroxide ion is (A) O 2< O 2-< O 22- (B) O 2> O 2-> O 22- (C) O 2< O 2-> O 22- (D) O 2> O 2-< O 22-

Bond strength depends on bond order. More is the bond order, more is the strength. Species Bond Order O2 2 O2- 1.5 O22- 1.0 Hence, the order of bond strength is as: O 2> O 2-> O 22-

Species	Bond Order
$O_{2}$	$2$
$O_{2}^{-}$	$1.5$
$O_{2}^{2 -}$	$1.0$

Q. The order of relative bond strength of oxygen molecule, superoxide ion and peroxide ion is

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

$O_{2} > O_{2}^{-} > O_{2}^{2 -}$

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

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

Bond strength depends on bond order. More is the bond order, more is the strength.

Species Bond Order

$O_{2}$ $2$

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

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

Hence, the order of bond strength is as : $O_{2} > O_{2}^{-} > O_{2}^{2 -}$

Q. The order of relative bond strength of oxygen molecule, superoxide ion and peroxide ion is

O2​<O2−​<O22−​

O2​>O2−​>O22−​

O2​<O2−​>O22−​

O2​>O2−​<O22−​

Bond strength depends on bond order. More is the bond order, more is the strength. Species Bond Order O2​ 2 O2−​ 1.5 O22−​ 1.0 Hence, the order of bond strength is as : O2​>O2−​>O22−​

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

$O_{2} > O_{2}^{-} > O_{2}^{2 -}$

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

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

Bond strength depends on bond order. More is the bond order, more is the strength.

Species Bond Order

$O_{2}$ $2$

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

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

Hence, the order of bond strength is as : $O_{2} > O_{2}^{-} > O_{2}^{2 -}$
