According to "molecular orbital theory", which among the following diatomic molecules only has \(\pi\)-bonds?
- A \(\mathrm{N}_2\)
- B \(\mathrm{H}_2\)
- C \(\mathrm{C}_2\)
- D \(\mathrm{Be}_2\)
Answer & Solution
Correct Answer
(C) \(\mathrm{C}_2\)
Step-by-step Solution
Detailed explanation
Molecular orbital configuration of \(\mathrm{C}_2\) is \(\sigma l s^2 \sigma * 1 s^2 \sigma 2 s^2 \sigma * 2 s^2 \pi 2 p_x^2=\pi 2 p_y^2\) So, \(\mathrm{C}_2\) molecule contains only \(\pi\)-bonds.
