Hybridization of [Co(NH3)6]2+

The hybridization of a molecule or ion determines its shape and the nature of its chemical bonds. In the case of [Co(NH3)6]2+, the central cobalt atom is bonded to six ammonia ligands, resulting in an octahedral coordination geometry. To understand the hybridization of the central cobalt atom, we need to consider the valence bond theory.

Valence Bond Theory

The valence bond theory explains chemical bonding by considering the overlap of atomic orbitals. According to this theory, the atomic orbitals of the atoms participating in bonding overlap to form new hybrid orbitals. These hybrid orbitals then overlap with the orbitals of other atoms to form covalent bonds.

Hybridization of [Co(NH3)6]2+

The hybridization of the central cobalt atom in [Co(NH3)6]2+ can be determined by counting the number of electron pairs around the cobalt atom and the number of σ bonds it forms. In this case, the cobalt atom is surrounded by six ammonia ligands, each donating a pair of electrons. Hence, there are six electron pairs around the cobalt atom.

To accommodate these six electron pairs, the cobalt atom undergoes sp3d2 hybridization. This means that the cobalt atom's 4s, 4p, and 4d orbitals hybridize to form six sp3d2 hybrid orbitals. These hybrid orbitals are directed towards the corners of an octahedron, which corresponds to the arrangement of the ammonia ligands around the cobalt atom.

Visual Representation of Hybridization

To visually represent the hybridization of [Co(NH3)6]2+, we can draw an energy diagram showing the mixing of the atomic orbitals to form the hybrid orbitals. Here is a simplified representation of the hybridization process:

- The cobalt atom's 4s, 4p, and 4d orbitals mix to form six sp3d2 hybrid orbitals.
- These hybrid orbitals are directed towards the corners of an octahedron.
- Each ammonia ligand donates a pair of electrons to form a σ bond with the cobalt atom.
- The resulting molecule, [Co(NH3)6]2+, adopts an octahedral shape.

Conclusion

In summary, the central cobalt atom in [Co(NH3)6]2+ undergoes sp3d2 hybridization to form six sp3d2 hybrid orbitals. These hybrid orbitals are directed towards the corners of an octahedron, accommodating the six ammonia ligands. Understanding the hybridization of a molecule or ion helps us explain its shape and the nature of its chemical bonds.

In co+2 the electronic configuration is 3d7 4s0 and here the NH3 will acts as a strong field ligand ( exceptionally) , hence ut will make sure to pairing of the 6 electron rest of the one electron will move to the 5s orbital and according to VBT it will form inner orbital complex ( octahedral) with d2sp3 hybridization
