Vedclass · Answer

(C) According to Molecular Orbital Theory $(MOT)$,we determine the presence of unpaired electrons by filling the molecular orbitals:$1$. For $N_2^+$ ($13$ electrons): $\sigma_{1s}^2 \sigma_{1s}^{*2} \sigma_{2s}^2 \sigma_{2s}^{*2} \pi_{2p_x}^2 \pi_{2p_y}^2 \sigma_{2p_z}^1$. It has $1$ unpaired electron.$2$. For $O_2$ ($16$ electrons): $\sigma_{1s}^2 \sigma_{1s}^{*2} \sigma_{2s}^2 \sigma_{2s}^{*2} \sigma_{2p_z}^2 \pi_{2p_x}^2 \pi_{2p_y}^2 \pi_{2p_x}^{*1} \pi_{2p_y}^{*1}$. It has $2$ unpaired electrons.$3$. For $O_2^{2-}$ ($18$ electrons): $\sigma_{1s}^2 \sigma_{1s}^{*2} \sigma_{2s}^2 \sigma_{2s}^{*2} \sigma_{2p_z}^2 \pi_{2p_x}^2 \pi_{2p_y}^2 \pi_{2p_x}^{*2} \pi_{2p_y}^{*2}$. All electrons are paired.$4$. For $B_2$ ($10$ electrons): $\sigma_{1s}^2 \sigma_{1s}^{*2} \sigma_{2s}^2 \sigma_{2s}^{*2} \pi_{2p_x}^1 \pi_{2p_y}^1$. It has $2$ unpaired electrons.Therefore,$O_2^{2-}$ is the only species without unpaired electrons.

Which of the following molecules/ions does not contain unpaired electrons?
