Homework Help: Mixing and paramagnetism

  1. May 4, 2015 #1
    1. The problem statement, all variables and given/known data
    Assuming 2s-2p mixing is not operative, the paramagnetic species among the following is
    1. Be2
    2. B2
    3. C2
    4. N2

    2. Relevant equations

    3. 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.

    What is that statement 2s and 2p is not operative meaning?
  5. May 4, 2015 #4
    [What I think] 2s-2p mixing is not operative may mean that hybridization is not done (which is a vsepr concept).
