Question:medium

In which of the following conversions decrease in bond order is observed?
(I) \( O_2 \rightarrow O_2^- \)
(II) \( O_2 \rightarrow O_2^{2-} \)
(III) \( C_2 \rightarrow C_2^{2-} \)
(IV) \( N_2 \rightarrow N_2^+ \)

Show Hint

Adding electrons to antibonding orbitals decreases bond order, while removing electrons from bonding orbitals also decreases bond order.
