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): In the diamagnetic octahedral complex, [Co(NH3)6]3+, the cobalt ion is in +3 oxidation state.
Reason (R): Six pairs of electrons, one from each NH3 molecule, occupy the six hybrid orbitals.
  • 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.

Explanation:

Assertion and Reason Clarification:
- The assertion states that in the diamagnetic octahedral complex, [Co(NH3)6]3+, the cobalt ion is in +3 oxidation state.
- The reason given is that six pairs of electrons, one from each NH3 molecule, occupy the six hybrid orbitals.

Analysis:
- The assertion is correct because the oxidation state of cobalt in [Co(NH3)6]3+ is indeed +3.
- The reason is also correct as each NH3 molecule donates a lone pair of electrons to form coordinate bonds with cobalt, resulting in the occupation of the six hybrid orbitals.

Explanation of Correct Answer:
- Option 'B' is the correct answer because both the assertion and reason are factually correct statements.
- The reason provided is a valid explanation for the assertion as the occupation of the six hybrid orbitals by electron pairs from NH3 molecules is directly related to the +3 oxidation state of cobalt in the complex.

In conclusion, the correct answer is option 'B' as both the assertion and reason are correct, and the reason effectively explains the assertion in the context of the coordination complex [Co(NH3)6]3+.
