Which of the following is a wrong order with respect to the property mentioned against each?

The order ${\mathrm{O}}_2^{2-}>{\mathrm{O}}_2>{\mathrm{O}}_2^{++}$ [ for paramagnetic moment] is wrong.

${\mathrm{O}}_2$ and ${\mathrm{O}}_2^{-}$ are paramagnetic while ${\mathrm{O}}_2^{2-}$  is diamagnetic.

If unpaired electrons are present in an ion/molecule, then it is paramagnetic. If all electrons are paired, then the ion/molecule is diamagnetic

The value of dipole moment of these molecules can be given as,

${\mathrm{O}}_2^{2-}$ has $\mu =0,{\mathrm{O}}_2$ has $2.83\mathrm{BM},{\mathrm{O}}_2^{2+}$ has $\mu =0$.

Hence correct option is C.
