MCQ

Which of the following has the minimum bond length ?

A
$O_2^+$
B
$O_2^-$
✓
$O_2^{2-}$
D
$O_2$

✓

Answer

Correct option: C.

$O_2^{2-}$

c
Bond order of $O_{2}^{+}=\frac{10-5}{2}=2.5$

Bond order of $O_{2}=\frac{10-7}{2}=1.5$

Bond order of $O_{2}^{2-}=\frac{10-8}{2}=1$

Bond order of $O_{2}=\frac{10-6}{2}=2$

Maximum bond order $=$ minimum bond length.

Bond length is minimum for $O_{2}^{+}$
