Question
Which of the following is paramagnetic ?
Options
A.O2-
B.CN-
C.CO
D.NO+
Solution
O2- = σls2, σ*ls2, σ2s2, σ*2s2, π2p2x = π2p2z , π* 2p2y = π* 2p1y
(due to unpaired e- , it is paramiagnetic)All others contain all the electrons paired
CO : σls2, σ*ls2, σ2s2, π2p2y , = π2p2z , σ2p2x , σ*2s2
CN- : σls2, σ*ls2, σ2s2, σ*2s2, (π2p2y = π2p2z )σ2p2x
NO+ : σls2, σ*ls2, σ2s2, σ*2s2, σ2p2x (π2p2y = π2p2z )
(due to unpaired e- , it is paramiagnetic)All others contain all the electrons paired
CO : σls2, σ*ls2, σ2s2, π2p2y , = π2p2z , σ2p2x , σ*2s2
CN- : σls2, σ*ls2, σ2s2, σ*2s2, (π2p2y = π2p2z )σ2p2x
NO+ : σls2, σ*ls2, σ2s2, σ*2s2, σ2p2x (π2p2y = π2p2z )
