Q. The internuclear distances in $O - O$ bonds for
$O_{2}^{-}, O_{2}, O_{2}^{-}$ and $O_{2}^{2-}$ respectively are:

JEE MainJEE Main 2013Chemical Bonding and Molecular Structure

Solution:

The bond length follows the order
$O_{2}^{+} <\, O_{2} <\, O_{2}^{-} <\, O_{2}^{2-}$
According to this the possible values are
$1.12\mathring{A}, 1.21\mathring{A}, 1.30\mathring{A}, 1.49\mathring{A}$
