The bond order of which of the following two species is same?

The bond order of which of the following two species is same?
  1. $\mathrm{O}_2, \mathrm{~N}_2$
  2. $\mathrm{C}_2, \mathrm{O}_2$
  3. $\mathrm{B}_2, \mathrm{C}_2$
  4. $\mathrm{F}_2, \mathrm{C}_2$

Solution

$\begin{array}{|c|c|c|}\hline \text{Molecule} & \begin{array}{c} \text{Total no. of} \\ \text{electron} \end{array} & \text{Bond order} \\ \hline \mathrm{O}_2 & 16 & 2 \\ \hline \mathrm{~N}_2 & 14 & 3 \\ \hline \mathrm{C}_2 & 12 & 2 \\ \hline \mathrm{~B}_2 & 10 & 1 \\ \hline \mathrm{~F}_2 & 18 & 1 \\ \hline\end{array}$ $\mathrm{O}_2$ and $\mathrm{C}_2$ have same bond order.
