Assertion (A) Primary and secondary are the two types of linkages shown by coordination compounds.
Reason ( R) The ions/groups bound by the secondary linkages to the metal have characteristic spatial arrangements corresponding to different coordination numbers.

Options

A. Both Assertion and Reason are correct and Reason is the correct explanation of the correct explanation of the Assertion
B. Both Assertion and Reason are correct but reason is not the correct explanation of Assertion
C. Assertion is correct but Reason is incorrect
D. Both Assertion and Reason are Incorrect

Answer

To analyze the given assertion and reason, we can break down the concepts involved:

### Step 1: Understanding the Assertion
The assertion states that "Primary and secondary are the two types of linkages shown by coordination compounds."

- **Explanation**: In coordination chemistry, linkages refer to the ways in which ligands (ions or molecules) are attached to a central metal atom. Primary linkages are those that involve the charge of the metal ion and are typically satisfied by anions. Secondary linkages, on the other hand, involve the coordination of ligands to the metal ion and relate to the geometry and spatial arrangement around the metal.

### Step 2: Understanding the Reason
The reason states that "The ions/groups bound by the secondary linkages to the metal have characteristic spatial arrangements corresponding to different coordination numbers."

- **Explanation**: This statement is true in the context of coordination compounds. The coordination number refers to the number of ligand atoms that are bonded to the central metal atom. Different coordination numbers lead to different geometrical arrangements (e.g., tetrahedral, octahedral, square planar) of the ligands around the metal ion.

### Step 3: Evaluating the Relationship between Assertion and Reason
Now we need to determine if the reason correctly explains the assertion.

- While both the assertion and reason are true statements, the reason does not directly explain the assertion. The assertion focuses on the types of linkages (primary and secondary), while the reason discusses the spatial arrangements related to secondary linkages. Therefore, the reason does not provide a justification for the assertion.

### Conclusion
- **Assertion (A)**: True
- **Reason (R)**: True
- **Explanation**: The reason does not correctly explain the assertion.

### Final Answer
The assertion is true, and the reason is true, but the reason is not the correct explanation of the assertion.
