[ CoF ₆ ]³⁻ : Outer orbital complex; d ² sp ³ hybridized D. [ FeF ₆ ]³⁻ : Outer orbital complex; sp ³ ~d ² hybridized E. [ Ni ( CN )₄ ]²⁻ : Inner orbital complex; sp ³ hybridized Choose the correct answer from the options given belo

Step-by-step solution

Analyzing each complex based on Valence Bond Theory (VBT): A. [Co(NH₃)₆]³⁺ : Co³⁺ is 3d^6 . NH₃ is a strong field ligand (SFL) for Co³⁺ , causing pairing. This leaves two 3d orbitals vacant. Hybridization is d^2sp^3 (Inner orbital complex). Statement A is correct. B. [MnCl₆]³⁻ : Mn³⁺ is 3d^4 . Cl^- is a weak field ligand (WFL). No pairing occurs. To accommodate 6 ligands, it uses 4s , 4p , and 4d orbitals. Hybridization is sp^3d^2 (Outer orbital complex). Statement B is correct. C. [CoF₆]³⁻ : Co³⁺ is 3d^6 . F^- is
