Consider that a \(d ^{6}\) metal ion \(\left( M ^{2+}\right)\) forms a complex with aqua ligands, and the spin only magnetic moment of the complex is \(4.90\) \(BM.\) The geometry and the crystal field stabilization energy of the complex is:
- A tetrahedral and \(-1.6 \Delta_{ t }+1 P\)
- B tetrahedral and \(-0.6 \Delta_{ t }\)
- C octahedral and \(-1.6 \Delta_{0}\)
- D octahedral and \(-2.4 \Delta_{0}+2 P\)
Answer & Solution
Correct Answer
(B) tetrahedral and \(-0.6 \Delta_{ t }\)
Step-by-step Solution
Detailed explanation
If spin only magnetic moment of the complex is \(4.90 BM ,\) it means number of unpaired electrons should be \(4.\) \((A)\) In octahedral complex: \(\left[ M \left( H _{2} O \right)_{6}\right]^{2+}\) \(C.F.S.E.\)…
