Question

Assertion (A): [Cr(H$_2$O)$_6$]Cl$_2$ and [Fe(H$_2$O)$_6$]Cl$_2$ are examples of homoleptic complexes.
Reason (R): All the ligands attached to the metal are the same.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Assertion (A) is false, but Reason (R) is true.

Hint:

Homoleptic complexes contain only one type of ligand bound to the central metal atom.

Answer 1

The Correct Option is A

To solve this question, let's analyze the assertion and reason provided.

Assertion (A):
[Cr(H₂O)₆]Cl₂ and [Fe(H₂O)₆]Cl₂ are examples of homoleptic complexes.

Reason (R):
All the ligands attached to the metal are the same.

1. Homoleptic Complexes:
Homoleptic complexes are those in which all the ligands attached to the central metal atom or ion are the same. In this case, both [Cr(H₂O)₆]Cl₂ and [Fe(H₂O)₆]Cl₂ have six water molecules (H₂O) as ligands, making them homoleptic complexes.

2. Evaluation of Assertion (A):
Both [Cr(H₂O)₆]Cl₂ and [Fe(H₂O)₆]Cl₂ contain the same type of ligand, H₂O. Therefore, Assertion (A) is correct.

3. Evaluation of Reason (R):
The reason states that all the ligands attached to the metal are the same, which is true in the case of homoleptic complexes. Therefore, Reason (R) is also correct.

4. Conclusion:
Both the assertion and the reason are correct, and the reason correctly explains the assertion.

Final Answer:
The correct option is that both the assertion and reason are true, and the reason explains the assertion.
