Which of the following configurations, forms an outer octahedral comp...
Explanation:
Octahedral Complex:
An octahedral complex is a type of coordination complex where a central metal atom is surrounded by six ligands in a symmetrical arrangement. The ligands are located at the corners of an octahedron.
Configurations of Transition Metals:
- Transition metals can have different electron configurations based on their oxidation states.
- The number of d electrons in the transition metal ion determines the type of complex it can form.
d8 Configuration:
- A d8 configuration corresponds to a metal ion with 8 electrons in its d orbital.
- This configuration forms an outer octahedral complex because all 6 ligands can be accommodated in the d orbitals without any pairing of electrons.
- The ligands occupy the eg orbitals in an octahedral complex.
Correct Answer:
- The correct answer is option 'B' (d8) because a d8 configuration forms an outer octahedral complex.
- Options 'a' (d4) and 'c' (d6) would involve electron pairing, which is not favored in an outer octahedral complex.
Therefore, a d8 configuration is the only one among the given options that forms an outer octahedral complex.

D4: Forms outer complex in high spin and forms inner complex in low spin. It cannot form octahedral complex.
d6 : In low spin it forms inner octahedral complex and in high spin forms outer octahedral complex.
d8 : Forms only outer high spin octahedral complex.
