Which of the following has the minimum bond length?

As we learnt in

Bond Order -

Bond order is defined as one half the difference between the number of electrons present in the bonding and the antibonding orbitals.

- wherein

$Bond \:Order=\frac{N_{b}-{N_{a}}}{2}$
We know that bond order $\propto \frac{1}{Bond\: Length}$

of all the species given, $O_{2}^{+}$ has the highest bond order at 2.5 thereby giving it the lowest bond length.

Option 1)

$O_{2}^{+}$

This is the correct option

Option 2)

$O_{2}^{-}$

This is an incorrect option

Option 3)

$O_{2}^{2-}$

This is an incorrect option

Option 4)

$O_{2}$

This is an incorrect option
