What is the value of effective magnetic moment found in \(+3\) oxidation state of Chromium \((\mathrm{Z}=24) ?\)
- A \(1.73 \mathrm{BM}\)
- B \(3.87 \mathrm{BM}\)
- C \(4.90 \mathrm{BM}\)
- D \(2.84 \mathrm{BM}\)
Answer & Solution
Correct Answer
(B) \(3.87 \mathrm{BM}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{Cr}^{3+} \longrightarrow 3 \mathrm{~d}^{3}\) (3 unpaired electrons)
\(\therefore \mu=\sqrt{\mathrm{n}(\mathrm{n}+2)}=\sqrt{3(3+2)}=3.87 \mathrm{BM}\)
\(\therefore \mu=\sqrt{\mathrm{n}(\mathrm{n}+2)}=\sqrt{3(3+2)}=3.87 \mathrm{BM}\)
