Correct answer
ANO NO+
Step-by-step explanation
Molecular orbital configuration of NO (15 electrons) is
Nb = 10
Na = 5
BO = = 2.5
And in NO one unpaired electron is present , so it is paramagnetic.
Similarly Molecular orbital configuration of NO+ (14 electrons) is
Nb = 10
Na = 4
BO = = 3
And in NO+ no unpaired electron is present , so it is diamagnetic.
Nb = 10
Na = 5
BO = = 2.5
And in NO one unpaired electron is present , so it is paramagnetic.
