We know that,For O2+
Molecular orbital configuration of O2+ is σ1s2σ*1s2σ2s2σ*2s2σ2pz2π2px2≈π2py2π*2px1
Number of electrons in bonding orbital =10
Number of electrons in antibonding orbital =5
Bond order of NO2+=

10−5

2

=2.5
For NO+
Molecular orbital configuration is σ1s2σ*1s2σ2s2σ*2s2π2px2π2py2σ2pz2
Number of electrons in bonding orbital =10
Number of electrons in antibonding orbital =4
Bond order =

10−4

2

=3
So, O2+and NO+does not have same bond order.
