Exploring Paramagnetism in Molecules: Be2, B2, C2, and N2

In summary, the statement is discussing paramagnetic species among a list of molecules and suggests using the molecular orbital theory to determine the answer. The concept of 2s-2p mixing not being operative may refer to the lack of hybridization in these molecules. The correct answer is C2, which has unpaired electrons and is therefore paramagnetic.

What is that statement 2s and 2p is not operative meaning?
 
  • #4
[What I think] 2s-2p mixing is not operative may mean that hybridization is not done (which is a vsepr concept).

What is mixing?

Mixing is the process of combining two or more substances together to create a new mixture. This can be done by physically stirring or shaking the substances, or by chemical reactions.

What is paramagnetism?

Paramagnetism is a type of magnetism where certain materials are weakly attracted to a magnetic field. This is due to the alignment of unpaired electrons within the material.

How does mixing affect paramagnetism?

Mixing different substances can alter the paramagnetic properties of the resulting mixture. This is because the alignment of unpaired electrons can change when different substances are combined.

What are some examples of paramagnetic materials?

Some examples of paramagnetic materials include oxygen, aluminum, and platinum. These materials have unpaired electrons that are easily influenced by magnetic fields.

Can paramagnetism be controlled?

Yes, paramagnetism can be controlled through the use of external magnetic fields. This is often used in industrial processes to separate paramagnetic materials from non-magnetic substances.
