Using MOT, compare $O_2^{+}$ and $O_2^{-}$ species and choose the incorrect option

• A. $O_2^{+}$ have higher bond order than $O_2^{-}$
• B. $O_2^{-}$ Is less stable
• C. $O_2^{+}$ Is diamagnetic while $O_2^{-}$ is paramagnetic
• D. Both $O_2^{+}$ and $O_2^{-}$ are paramagnetic

Answer 1

The correct option is C

$O_2^{+}$ Is diamagnetic while $O_2^{-}$ is paramagnetic

$O_2^{+}$ has 15 electrons and $O_2^{-}$ has 17 electrons, both of them are paramagnetic
