Question
[Co(NH3)6]3+ and [CoF6]3– are respectively known as: (A) Spin free Complex, Spin paired Complex (B) Spin paired Complex, Spin free Complex (C) Outer orbital Complex, Inner orbital Complex (D) Inner orbital Complex, Spin paired Complex
Answer: B
💡 Solution & Explanation
[Co(NH3)6]3+ Co3+ (strong field ligand) 3d6 g g t ,e 0 , Hybridisation : d2sp3 Inner obital complex(spin paired complex) Pairing will take place. [CoF6]3– Co3+ (weak field ligand) 3d6 g g t ,e 2 Hybridisation : sp3d2 Outer orbital complex (spin free complex) no pairing will take place
