Thus, all these are isoelectronic. MO electronic configuration is
No electron unpaired - diamagnetic
Bonding electrons = 10
Anti-bonding electrons = 4
Thus, bond- order =

Common Features among CN-, CO, NO, and N2

1. Isoelectronic
- All four species, CN-, CO, NO, and N2, have the same number of electrons.
- CN- has 10 valence electrons (5 from carbon and 5 from nitrogen), CO has 10 valence electrons (4 from carbon and 6 from oxygen), NO has 11 valence electrons (5 from nitrogen and 6 from oxygen), and N2 has 10 valence electrons (5 from each nitrogen atom).
- They are all isoelectronic with 10 valence electrons.

2. Diamagnetic
- Diamagnetic substances have all their electrons paired up and do not possess any unpaired electrons.
- CN-, CO, NO, and N2 all have all their electrons paired up and do not exhibit any unpaired electrons.
- Therefore, they are all diamagnetic in nature.

3. Bond Order Two
- Bond order is a measure of the stability of a covalent bond.
- It can be calculated using the formula: Bond Order = (Number of bonding electrons - Number of antibonding electrons) / 2.
- CN-, CO, NO, and N2 all have a bond order of two.
- CN- has a triple bond between carbon and nitrogen (C≡N), CO has a triple bond between carbon and oxygen (C≡O), NO has a double bond between nitrogen and oxygen (N=O), and N2 has a triple bond between the two nitrogen atoms (N≡N).
- In all cases, the number of bonding electrons is greater than the number of antibonding electrons, resulting in a bond order of two.

Conclusion
- The common features among CN-, CO, NO, and N2 are that they are isoelectronic, diamagnetic, and have a bond order of two.
- These similarities arise due to the similar number of valence electrons and the type of bonds present in these species.
