Solution

Q.
In which of the following processes, the bond order increases and paramagnetic character changes to diamagnetic one [2023]

1 $N_{2} \to N_{2}^{+}$

2 $NO \to {NO}^{+}$

3 $O_{2} \to O_{2}^{+}$

4 $O_{2} \to O_{2}^{2 -}$

Ans.
(2)

NO is paramagnetic with B.O = 2.5, ${NO}^{+}$ is diamagnetic with B.O = 3.
