\([Co(NH_3)_6]^{3+} \text{is} \) ________\(\text{hybridised and}\)________
\(d^2sp^3\), Diamagnetic
\(d^2sp^3\), Paramagnetic
\(sp^3d^2\), Diamagnetic
\(sp^3d^2\), Paramagnetic
The Correct Option is C
Solution and Explanation
The correct option is (c ): \(sp^3d^2\text{and Diamagnetic}\)
In [Co (NH3)6]3+, Co is in +3 oxidation state with the configuration 3d6. In the presence of NH3 a strong ligand, the 3d electrons pair up leaving two d-orbitals empty.
Hence, the hybridization is sp3d2 forming an inner orbital octahedral complex.

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
