M.O. configuration of NO +is σ 1 s2, σ* 1 s2, σ 2 s2, σ* 2 s2, π 2 px2 ≈ π 2 py2, π 2 pz2 and M.O. configuration of NO is σ 1 s2, σ* 1 s2, σ 2 s2, σ* 2 s2, π 2 px2 ≈ π 2 py2, π* 2 px1

Q. In the change of $NO \to N O^{+}$ the electron is added to

$σ$ - orbital

$π$ - orbital

$σ^{*}$ - orbital

$π^{*}$ - orbital

M.O. configuration of $N O^{+}$ is
$σ 1 s^{2}, σ^{} 1 s^{2}, σ 2 s^{2}, σ^{} 2 s^{2}, π 2 p_{x}^{2} \approx π 2 p_{y}^{2}, π 2 p_{z}^{2}$
and M.O. configuration of $NO$ is
$σ 1 s^{2}, σ^{} 1 s^{2}, σ 2 s^{2}, σ^{} 2 s^{2}, π 2 p_{x}^{2} \approx π 2 p_{y}^{2}, π^{*} 2 p_{x}^{1}$

Q. In the change of NO→NO+ the electron is added to

σ - orbital

π - orbital

σ∗ - orbital

π∗ - orbital
