Identify the number of unpaired electrons present and the geometry respectively of a complex [ CoF ₆ ]³⁻( given atomic number Co =27 )
Options
- A4, Octahedral
- B2 , trigonal bipyramidal
- C0 , Octahedral
- D0 , trigonal bipyramidal
Correct answer
A. 4, Octahedral
Step-by-step solution
In the presence of F ^ Weak field ligand electronic configuration remains same No of unpaired e ⁻=4 and hybridisation is sp ^3 ~d ^2 , octahedral geometry
