  2. B \(\sigma-\sigma^{*}\) संक्रमण
  3. C \(M \rightarrow L\) आवेश स्थानांतरण संक्रमण
  4. D \(d - d\) संक्रमण
Verified Solution

Answer & Solution

Correct Answer

(A) \(L \rightarrow M\) आवेश स्थानांतरण संक्रमण

Step-by-step Solution

Detailed explanation

\(K M n O_{4} \rightarrow K^{+}+M n O_{4}^{-}\) \(\therefore \ln M n O_{4}^{-},\) Mn has \(+7\) oxidation state having no electron in d-orbitals. It ts considered that higher the oxidation state of metal, greater is the tendency to occur \(L \rightarrow M\) charge transfer,…
