  2. B \(\mathrm{CN}^{-}\)and \(\mathrm{CO}\)
  3. C \(\mathrm{O}_2^{2-}\) and \(\mathrm{B}_2\)
  4. D \(\mathrm{O}_2^{+}\)and \(\mathrm{NO}^{+}\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(\mathrm{O}_2^{+}\)and \(\mathrm{NO}^{+}\)

Step-by-step Solution

Detailed explanation

We know that, For \(\mathrm{O}_2^{+}\) Molecular orbital configuration of \(\mathrm{O}_2^{+}\)is \(\sigma \mathrm{l} s^2 \sigma^* 1 s^2 \sigma 2 s^2 \sigma^* 2 s^2 \sigma 2 p_z^2 \pi 2 p_x^2 \approx \pi 2 p_y^2 \pi^* 2 p_x^1\) Number of electrons in bonding orbital \(=10\)…
