Question:

Assertion (A): [Cr(H_2O)_6]Cl_2 and [Fe(H_2O)_6]Cl_2 are examples of homoleptic complexes.
Reason (R): All the ligands attached to the metal are the same.

Show Hint

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

The Correct Option is A

Solution and Explanation

Homoleptic Complexes

Step 1: Understanding homoleptic complexes. Homoleptic complexes are those in which all the ligands attached to the central metal atom are the same. Both \([Cr(H_2O)_6]Cl_2\) and \([Fe(H_2O)_6]Cl_2\) are examples of homoleptic complexes, as all the ligands in each complex are water molecules.

Step 2: Conclusion. Since Assertion (A) is true, and Reason (R) correctly explains it, the correct answer is option (A).
