Question

$[Co(NH_3)_6]^{3+} \text{is}$ $\text{hybridised and}$

$d^2sp^3$ , Diamagnetic

$d^2sp^3$ , Paramagnetic

$sp^3d^2$ , Diamagnetic

$sp^3d^2$ , Paramagnetic

Answer

$sp^3d^2$ , Diamagnetic

Explanation

Solution

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.
