Identify the number of unpaired electrons present and geometry respectively of [ Co ( NH ₃ )₆ ]³⁺ complex.
Options
- A0 , square planar
- B2, square planar
- C4, octahedral
- D0 , octahedral
Correct answer
D. 0 , octahedral
Step-by-step solution
[ Co ( NH ₃ )₆ ]³⁺ Oxidation state of Co =+3 Electronic configuration of Co ⁺³=[ Ar ] 3 ~d ^6 4 ~s ^ NH ₃ is strong field ligand. Pairing will take place. No. of unpaired electrons =0 . Geometry: Octahedral
