Question
Assuming 2s-2p mixing is NOT operative, the paramagnetic species among the following is
Options
A.Be2
B.B2
C.C2
D.N2
Solution
Be2 = σ1s2σ*1s2σ2s2σ*2s2
B2 = σ1s2σ*1s2σ2s2σ*2s2σ2pz2
C2 = σ1s2σ*1s2σ2s2σ*2s2σ2pz2π2px1π2py1
N2 = σ1s2σ*1s2σ2s2σ*2s2σ2pz2π2px2π2py2
B2 = σ1s2σ*1s2σ2s2σ*2s2σ2pz2
C2 = σ1s2σ*1s2σ2s2σ*2s2σ2pz2π2px1π2py1
N2 = σ1s2σ*1s2σ2s2σ*2s2σ2pz2π2px2π2py2
