The changes in bond length with respect to \(\mathrm{N}-\mathrm{N}\) and \(\mathrm{O}-\mathrm{O}\), when \(\mathrm{N}_2\) becomes \(\mathrm{N}_2^{+}\)and \(\mathrm{O}_2\) becomes \(\mathrm{O}_2^{+}\)are respectively
- A increases, decreases
- B decreases, increases
- C increases, increases
- D decreases, decreases
Answer & Solution
Correct Answer
(A) increases, decreases
Step-by-step Solution
Detailed explanation
\[ \begin{aligned} \mathrm{N}_2(14) \rightarrow \sigma 1 s^2 < \stackrel{*}{\sigma} 1 s^2 < \sigma 2 s^2 < \stackrel{*}{\sigma} 2 s^2 & < \pi 2 p_x^2 \\ & \approx \pi 2 p_y^2 < \sigma 2 p_z^2 \end{aligned} \] Bond order \(=\frac{10-4}{2}=3\)…
