Expert Answer
O2 = (σ1s)2(σ*1s)2 (σ2s)2(σ*2s)2(σ2z)2(π2px2= π2py2) (π*2px1= π*2py1)
Bond order = (Nb-Na) /2 = (10-6)/2= 2
It is paramagnetic as it contains two unpaired electrons.
O2+ = = (σ1s)2(σ*1s)2 (σ2s)2(σ*2s)2(σ2z)2(π2px2= π2py2) (π*2px1)
Bond order = 2.5
It is paramagnetic as it contains one unpaired electron.
O2+ = = (σ1s)2(σ*1s)2 (σ2s)2(σ*2s)2(σ2z)2(π2px2= π2py2) (π*2px2= π*2py1)
Bond order = 1.5
It is paramagnetic as it contains one unpaired electron.
