Question

The spin-only magnetic moment of Hexacyanomanganate(II) ion is.........BM

• A. 5.90 BM
• B. 1.73 BM
• C. 4.90 BM
• D. 3.87 BM

Answer 1

The Correct Option is A

\(\text{The spin-only magnetic moment is calculated using the formula:} \\ \mu = \sqrt{n(n + 2)} \, \text{BM} \\ \text{where } n \text{ is the number of unpaired electrons. For } \text{Mn}^{2+}, \, n = 5, \text{ so:} \\ \mu = \sqrt{5(5 + 2)} = \sqrt{35} \approx 5.92 \, \text{BM}\)
