Bond length decreases with an increase in bond order. Therefore, the order of bond length in these species is O 2+< O 2-> O 2 < O 22- O 2+ (bond order -=2 ⋅ 5, O 2=2, O 2-=1 ⋅ 5, O 2 2-=1 )

Q. Which of the following shows correct order of bond length?

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

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

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

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

Bond length decreases with an increase in bond order. Therefore, the order of bond length in these species is
$O_{2}^{+} < O_{2}^{-} > O_{2} < O_{2}^{2 -} O_{2}^{+} < b r / >$ (bond order $- = 2 \cdot 5, O_{2} = 2, O_{2}^{-} = 1 \cdot 5, O_{2}^{2 -} = 1$ )

Q. Which of the following shows correct order of bond length?

O2+​>O2​>O2−​>O2​2−

O2​+<O2​−>O2​<O2​2−

O2+​>O2​<O2−​>O22−​

O2​+>O2​>O2​−>O2​2−

Bond length decreases with an increase in bond order. Therefore, the order of bond length in these species is O2+​<O2−​>O2​<O22−​O2+​<br/>(bond order −=2⋅5,O2​=2,O2−​=1⋅5,O2​2−=1 )

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

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

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

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

Bond length decreases with an increase in bond order. Therefore, the order of bond length in these species is
$O_{2}^{+} < O_{2}^{-} > O_{2} < O_{2}^{2 -} O_{2}^{+} < b r / >$ (bond order $- = 2 \cdot 5, O_{2} = 2, O_{2}^{-} = 1 \cdot 5, O_{2}^{2 -} = 1$ )
