Question

X, Y are the complexes of \(M^{n+}\) ion. The spin only magnetic moment values of X, Y respectively are 3.87 BM, 1.73 BM. \(M^{n+}\) is:

• A. \(Mn^{2+}\)
• B. \(Co^{2+}\)
• C. \(Fe^{2+}\)
• D. \(Cr^{3+}\)

Hint:

Remember: \[ 1.73 \rightarrow 1 \text{ unpaired electron} \] \[ 2.83 \rightarrow 2 \text{ unpaired electrons} \] \[ 3.87 \rightarrow 3 \text{ unpaired electrons} \]

Answer 1

The Correct Option is C
