The molecule/ion having paramagnetic nature and a bond order of 1.0 is
- A \(\mathrm{He}_2^{+}\)
- B \(\mathrm{Li}_2^{+}\)
- C \(\mathrm{B}_2\)
- D \(\mathrm{C}_2\)
Answer & Solution
Correct Answer
(C) \(\mathrm{B}_2\)
Step-by-step Solution
Detailed explanation
\(\mathrm{He}_2^{+}=\sigma s^2 < \sigma^* \mathrm{l} s^1\) \(\mathrm{BO}=\frac{2-1}{2}=0.5\) \(\mathrm{He}_2^{+}\)ion having one unpaired electron. So, it is paramagnetic.…
