A) 2
B) 2.5
C) 3
D) none of these
Correct Answer: C
Solution :
\[{{N}_{2}}\]molecule, according to MOT, \[\sigma 1{{s}^{2}},{{\sigma }^{*}}1{{s}^{2}},\sigma 2{{s}^{2}},{{\sigma }^{*}}2{{s}^{2}},\left\{ \begin{matrix} \pi 2p_{y}^{2} \\ \pi 2p_{z}^{2} \\ \end{matrix} \right.,\sigma 2p_{x}^{2}\] No. of bonding electrons \[Bond\text{ }order=\frac{No.\text{ }of\text{ }antibonding\text{ }electrons}{2}\] \[=\frac{10-4}{2}=\frac{6}{2}=3\]
