Question

The electronic configuration of $O _{2}$ 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_{x}^{2

Vedclass · Accepted Answer

$\pi * 2 p_{x}$

Vedclass · Answer

The electronic configuration of $O _{2}$ is,

$\sigma 1 s^{2} \sigma^{*} 1 s^{2} \sigma 2 s^{2} \sigma^{*} 2 s^{2} \sigma 2 p_{z}^{2} \pi 2 p_{x}^{2}=\pi 2 p_{y}^{2} \pi * 2 p_{x}^{1}=\pi * 2 p_{y}^{1}$

When electron is added in $O _{2}$ to form $O _{2}^{-},$ the added electron goes to $\pi * 2 p_{x}$ or $\pi * 2 p_{y}$

Thus, option $( C )$ is correct.

List$-I$	List$-II$
$(a)$ $Ne _{2}$	$(i)$ $1$
$(b)$ $N _{2}$	$(ii)$ $2$
$(c)$ $F _{2}$	$(iii)$ $0$
$(d)$ $O _{2}$	$(iv)$ $3$

During the change of $O _{2}$ to $O _{2}^{-}$, the incoming electron goes to the orbital :
