4.Chemical Bonding and Molecular Structure
medium
$O _{2}$ થી $O _{2}^{-}$ ના પરિવર્તન દરમિયાન આવતા ઇલેક્ટ્રોન કઈ ભ્રમણકક્ષામાં જાય છે:
A
$\pi 2 p_{y}$
B
$\sigma^{*} 2 p_{z}$
C
$\pi * 2 p_{x}$
D
$\pi 2 p_{x}$
(AIIMS-2019)
Solution
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.
