The spin-only magnetic moment value of \(\mathrm{B}_{2}^{+}\) species is \(......\,\times 10^{-2} \,\mathrm{BM}\). (Nearest integer) [Given : \(\sqrt{3}=1.73\) ]
- A \(243\)
- B \(1\)
- C \(173\)
- D \(143\)
Answer & Solution
Correct Answer
(C) \(173\)
Step-by-step Solution
Detailed explanation
\(\mathrm{B}_{2}^{+} \Rightarrow \sigma_{1 \mathrm{~s}}^{2} \sigma_{1 \mathrm{~s}}^{* 2} \sigma_{2 s}^{2} \sigma_{2 \mathrm{~s}}^{* 2} \pi_{2 \mathrm{py}}^{1} \simeq \pi_{2 \mathrm{pz}}^{0}\) \(\Rightarrow 9 \mathrm{e}^{-}\) \(\mu=\sqrt{1(1+2)}=\sqrt{3}\, \mathrm{BM}\)…
