$1.5$ and paramagnetic

Vedclass · Answer

$\mathrm{O}_{2}^{-}=\left(\sigma_{1 \mathrm{~s}}ight)^{2}\left(\sigma_{1 \mathrm{~s}}^{*}ight)^{2}\left(\sigma_{2 \mathrm{~s}}ight)^{2}\left(\sigma_{2 \mathrm{~s}}^{*}ight)^{2}\left(\sigma_{2 \mathrm{p}_{\mathrm{z}}}ight)^{2}$

$\left(\pi_{2 \mathrm{p}_{\mathrm{x}}}^{2}=\pi_{2 \mathrm{p}_{\mathrm{y}}}^{2}ight)\left(\pi_{2 \mathrm{p}_{\mathrm{x}}}^{*_{2}}=\pi_{2 \mathrm{p}_{\mathrm{y}}}^{*_{1}}ight)$

$	ext { Bond order }=\frac{10-7}{2}=1.5$

and paramagnetic

The bond order and magnetic behaviour of $\mathrm{O}_{2}^{-}$ion are, respectively:
