$O_2$

Vedclass · Answer

(C) The electronic configuration of the $O_2$ molecule is $(\sigma 1s)^2 (\sigma^* 1s)^2 (\sigma 2s)^2 (\sigma^* 2s)^2 (\sigma 2p_z)^2 (\pi 2p_x)^2 (\pi 2p_y)^2 (\pi^* 2p_x)^1 (\pi^* 2p_y)^1$. Bond order is calculated as $\frac{N_b - N_a}{2}$,where $N_b$ is the number of bonding electrons and $N_a$ is the number of antibonding electrons. For $O_2$,$N_b = 10$ and $N_a = 6$. Bond order $= \frac{10 - 6}{2} = \frac{4}{2} = 2$.

Which of the following molecules has a bond order of $2$?
