Which Molecules Exhibit Paramagnetism: Be2, B2, C2, or N2?

Click For Summary
SUMMARY

The discussion centers on identifying paramagnetic molecules among Be2, B2, C2, and N2, with a focus on the implications of 2s-2p mixing not being operative. It is established that C2 is the paramagnetic species due to the presence of unpaired electrons in its molecular orbital configuration. The concept of molecular orbital theory is crucial for understanding the electron arrangements that lead to paramagnetism in these molecules.

PREREQUISITES
  • Molecular orbital theory
  • Understanding of paramagnetism and unpaired electrons
  • Concept of hybridization
  • Basic knowledge of molecular structures
NEXT STEPS
  • Study molecular orbital theory in detail
  • Research the concept of unpaired electrons and their role in paramagnetism
  • Explore the effects of hybridization on molecular properties
  • Investigate the molecular structures of Be2, B2, C2, and N2
USEFUL FOR

Chemistry students, educators, and anyone interested in molecular properties and the principles of paramagnetism.

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?

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