Current Question (ID: 20964)

Question:

$\text{During the change of } \text{O}_2 \text{ to } \text{O}_2^{-}, \text{ the incoming electron that goes to the orbital is:}$

Options:

1. $\sigma^*_{2pz}$
2. $\pi_{2py}$
3. $\sigma_{2pz}$
4. $\pi^*_{2px}$

Solution:

$\text{Hint: Follow MOT diagram of } \text{O}_2$ $\text{For } \text{O}_2 \text{ and } \text{O}_2^{-} \text{ the electronic configuration is as follows:}$ $(\sigma_{2s})^2 (\sigma_{2s}^*)^2 (\sigma_{2pz})^2 (\pi_{2px})^2 (\pi_{2py})^2 (\pi_{2px}^*)^1 (\pi_{2py}^*)^1.$ $\text{In case of } \text{O}_2^{-}, \text{ extra electron added in } \pi^*_{2px} \text{ orbital. Hence, option fourth is the correct answer.}$
