Chemistry Question on Molecular Orbital Theory

Total number of antibonding electrons present in O2O_2 will be

A

6

B

8

C

4

D

2

Answer

6

Explanation

Solution

O2(σ1s)2(σ∗1s)2(σ2s)2(σ∗2s)2(σ2pz)2(π2px2=π2py2)(π∗2px1=π∗2py1)O _{2}(\sigma 1 s)^{2}\left(\sigma^{*} 1 s\right)^{2}(\sigma 2 s)^{2}\left(\sigma^{*} 2 s\right)^{2}\left(\sigma 2 p_{z}\right)^{2}\left(\pi 2 p_{x}^{2}=\pi 2 p_{y}^{2}\right)\left(\pi^{*} 2 p_{x}^{1}=\pi^{*} 2 p_{y}^{1}\right) Thus, there are total 6 electrons in antibonding orbitals.
