Chemistry Question on Chemical bonding and molecular structure

In the molecular orbital diagram for the molecular ion, N2+N_2{^{+}}, the number of electrons in the σ2p\sigma_{2p} molecular orbital is :

A

0

B

1

C

2

D

3

Answer

1

Explanation

Solution

The arrangement of electrons in molecular orbitals is as follows:

σ1s2, σ∗1s2, σ2s2, σ∗2s2, π2py2=π2pz2, σ2px1\sigma 1 s^{2},\, \sigma^{*} 1 s^{2},\, \sigma 2 s^{2},\, \sigma^{*} 2 s^{2},\, \pi 2 p_{y}^{2}=\pi 2 p_{z}^{2},\, \sigma 2 p_{x}^{1}
