Solution

The correct option is E None of the above
$O_{2} \to K K σ {(2 s)}^{2} σ^{} {(2 s)}^{2} σ {(2 p_{z})}^{2} π {(2 p_{x})}^{2} π {(2 p_{y})}^{2} π^{} {(2 p_{x})}^{1} σ^{} {(2 p_{y})}^{1}$

$O_{2}^{+} \to K K σ {(2 s)}^{2} σ^{} {(2 s)}^{2} σ {(2 p_{z})}^{2} π {(2 p_{x})}^{2} π {(2 p_{y})}^{2} π^{} {(2 p_{x})}^{1}$

$N_{2} \to K K σ {(2 s)}^{2} σ^{} {(2 s)}^{2} π {(2 p_{x})}^{2} π {(2 p_{y})}^{2} σ {(2 p_{z})}^{2}$

$N_{2}^{+} \to K K σ {(2 s)}^{2} σ^{*} {(2 s)}^{2} π {(2 p_{x})}^{2} π {(2 p_{y})}^{2} σ {(2 p_{z})}^{1}$
