  • Option 2)

    \text{C}_{2}^{2-}<\text{He}_{2}^{+}<\text{O}_{2}^{-}<\text{NO}

  • Option 3)

    \text{He}_{2}^{+}<\text{O}_{2}^{-}<\text{NO}<\text{C}_{2}^{2-}

  • Option 4)

    \text{NO}<\text{O}_{2}^{-}<\text{C}_{2}^{2-}<\text{He}_2^{+}

As learnt (Concept Missing)

Correct order of bond order is He^{2+}<O_{2}^{-}<NO<C_{2}^{2-}

 


Option 1)

\text{O}_{2}^{-}<\text{NO}<\text{C}_{2}^{2-}<\text{He}_2^{+}

This option is incorrect

Option 2)

\text{C}_{2}^{2-}<\text{He}_{2}^{+}<\text{O}_{2}^{-}<\text{NO}

This option is incorrect

Option 3)

\text{He}_{2}^{+}<\text{O}_{2}^{-}<\text{NO}<\text{C}_{2}^{2-}

This option is correct

Option 4)

\text{NO}<\text{O}_{2}^{-}<\text{C}_{2}^{2-}<\text{He}_2^{+}

This option is incorrect
