Which of the following species exhibits the diamagnetic behaviour ?

A

$NO$

B

$O_2^{2-}$

C

$O_2^+$

D

$O_2$

(AIEEE-2007)

Solution

$\quad O_{2}^{2}$ has $18$ electrons.

Moleculer orbital configuration of $O_{2}^{2-}$ is

$\sigma_{1 s^{2}} \sigma_{1 s^{2}}^{*} \sigma_{2 s^{2}} \sigma_{2 s^{2}}^{*} \sigma_{2 p_{z}^{2}} \pi_{2 p_{*}^{2}}$$=\pi_{2 p_{y}^{2}} \pi_{2 p_{z}^{2}}^{*}$$=\pi_{2 p_{y}^{2}}^{*}=\pi_{2 p_{y}^{2}}^{*}$
