[Raghav Gupta]

Homework Statement

Assuming 2s-2p mixing is not operative, the paramagnetic species among the following is
1. Be₂
2. B₂
3. C₂
4. N₂

Homework Equations

NA

The Attempt at a Solution

Not able to understand the statement "2s -2p mixing is not operative".
Can you help?
Paramagnetism is a specie having unpaired electron.
How to relate it here?

You can try molecular orbital theory.

You can try molecular orbital theory.

What is that statement 2s and 2p is not operative meaning?

 

[mooncrater]

[What I think] 2s-2p mixing is not operative may mean that hybridization is not done (which is a vsepr concept).
