Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Analyze [Mn(CN)\(_6\)]\(^{3-}\).
Strong field ligand CN\(^-\) → low-spin complex → inner orbital complex → d\(^2\)sp\(^3\) hybridization.
Step 2: Analyze [CoF\(_6\)]\(^{3-}\).
Weak field ligand F\(^-\) → high-spin complex → outer orbital complex → sp\(^3\)d\(^2\) hybridization.
Step 3: Confirm geometry.
Both complexes are octahedral, consistent with six-coordinate hybridization schemes.
Step 4: Conclusion.
\[ \boxed{[Mn(CN)_6]^{3-}: d^2sp^3, \quad [CoF_6]^{3-}: sp^3d^2} \]
Strong field ligand CN\(^-\) → low-spin complex → inner orbital complex → d\(^2\)sp\(^3\) hybridization.
