Read the passage given below and answer the following questions:
According to Valence Bond Theory, the metal atom or ion under the influence of ligands can use its (n−1)d, ns, np or ns, np, nd orbitals for hybridisation to yield a set of equivalent orbitals of definite geometry such as octahedral, tetrahedral, square planar and so on. These hybridised orbitals are allowed to overlap with ligand orbitals that can donate electron pairs for bonding. In these questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.
Assertion (A): The paramagnetic octahedral complex, [CoF6]3− uses outer orbital (4d) in hybridisation (sp3d2).
Reason (R): It is a high spin complex.
- a)Assertion and reason both are correct statements and reason is correct explanation for assertion.
- b)Assertion and reason both are correct statements but reason is not correct explanation for assertion.
- c)Assertion is correct statement but reason is wrong statement
- d)Assertion is wrong statement but reason is correct statement.

Valence Bond Theory and Hybridization
Valence Bond Theory explains the formation of chemical bonds between atoms by the overlap of atomic orbitals. According to this theory, in the presence of ligands, the metal atom or ion can use its (n−1)d, ns, np or ns, np, nd orbitals for hybridization. This yields a set of equivalent orbitals of definite geometry such as octahedral, tetrahedral, square planar, etc. These hybridized orbitals can overlap with ligand orbitals that donate electron pairs for bonding.
Assertion and Reason
The given assertion states that the paramagnetic octahedral complex, [CoF6]3− uses outer orbital (4d) in hybridization (sp3d2). The reason given for this is that it is a high spin complex.
Correct Answer and Explanation
The correct answer is option 'C' - Assertion is a correct statement, but the reason is a wrong statement.
Explanation:
The assertion is indeed correct because the paramagnetic complex, [CoF6]3− has a coordination number of 6 and an octahedral geometry. The hybridization of the central cobalt ion occurs using the outer d orbitals, as these orbitals have higher energy than the inner d orbitals. The hybridization of outer d orbitals with s and p orbitals leads to the formation of sp3d2 hybrid orbitals.
However, the reason given for the assertion is incorrect. The paramagnetism of [CoF6]3− is due to the presence of unpaired electrons in the d orbitals of the cobalt ion. This complex is a high spin complex because the crystal field splitting energy is less than the pairing energy, which means that the electrons prefer to remain unpaired in higher energy orbitals rather than being paired in lower energy orbitals.
Hence, the correct answer is option 'C' - Assertion is a correct statement, but the reason is a wrong statement.
