Q. Arrange $He_{2}^{+}, C_2^{2-}, O_2^-$ and $NO$ in increasing order of their bond orders.

Chemical Bonding and Molecular Structure

Solution:

\begin{aligned} &\begin{array}{|c|c|} \hline \text { Diatomic species } & \text { Bond order } \\ \hline \mathrm{NO} & 2.5 \\ \hline \mathrm{O}_{2}^{-} & 1.5 \\ \hline \mathrm{C}_{2}^{2-} & 3.0 \\ \hline \mathrm{He}_{2}{ }^{+} & 0.5 \\ \hline \end{array}\\ &\text { Thus, increasing order }\\ &\mathrm{He}_{2}^{+}<\mathrm{O}_{2}^{-}<\mathrm{NO}<\mathrm{C}_{2}^{2-} \end{aligned}
