Q.
Which amongst the following is incorrect statement [2022]

1 The bond orders of $O_{2}^{+}, O_{2}, O_{2}^{-} and O_{2}^{2 -}$ are 2.5, 2, 1.5 and 1, respectively.

2 $C_{2}$ molecule has four electrons in its two degenerate $π$ molecular orbitals.

3 $H_{2}^{+}$ ion has one electron.

4 $O_{2}^{+}$ ion is diamagnetic.

Ans.
(4)

$O_{2}^{+} : σ 1 s^{2} σ^{} 1 s^{2} σ 2 s^{2} σ^{} 2 s^{2} σ 2 p_{z}^{2} π 2 p_{x}^{2} = π 2 p_{y}^{2} π^{*} 2 p_{x}^{1}$

Due to the presence of one unpaired electron, $O_{2}^{+}$ is paramagnetic in nature.

Q. Which amongst the following is incorrect statement [2022]

1 The bond orders of O2+,O2,O2- and O22- are 2.5, 2, 1.5 and 1, respectively.

2 C2 molecule has four electrons in its two degenerate π molecular orbitals.

3 H2+ ion has one electron.

4 O2+ ion is diamagnetic.

Ans. (4) O2+ :σ1s2 σ*1s2 σ2s2 σ*2s2 σ2pz2 π2px2=π2py2 π*2px1 Due to the presence of one unpaired electron, O2+ is paramagnetic in nature.
