In the following

Answer :

The isoelectronic species have a similar bond order.

Both CN- and NO+ have 14 electrons.


Both CN- and NO+ have identical bond order i.e. 3.



(MOT diagram of CN-)


So, from the above diagram in CN-,


Electrons in bonding molecular orbitals = 8


Electrons in Anti Bonding Molecular orbitals = 2


Bond Order = .


= (8-2)


= 3



So, from the above MOT diagram of NO+,


Electrons in bonding molecular orbitals = 10(2e- in 1s)


Electrons in Anti Bonding Molecular orbitals = 4(2e- in 1*s)


Bond Order = .


= (10-4)


= 3.
