Options

A. If both `(A)` and ` (R )` are correct and `(R )` is the correct explanation of `(A ) ` .
B. If both `(A)` and ` (R )` are correct and `(R )` is the correct explanation of `(A ) ` .
C. If`(A)` is correct, but `( R )` is incorrect .
D. Both `(A)` and `(R ) ` are incorrect .

Answer

To solve the question, we need to analyze the assertion and reason provided:

### Step 1: Understand the Assertion
The assertion states that the ligands nitro and nitrito are called ambidentate ligands.
- **Ambidentate Ligands**: These are ligands that can coordinate to a metal ion through two different atoms. In this case, nitro (NO2) can bind through the nitrogen atom (N) or the oxygen atom (O).

### Step 2: Understand the Reason
The reason given is that these ligands give rise to linkage isomers.
- **Linkage Isomers**: These are isomers that differ in the point of attachment of a ligand to the central metal atom. For nitro and nitrito, when the nitrogen is bonded to the metal, it is called nitro, and when the oxygen is bonded, it is called nitrito.

### Step 3: Analyze the Relationship
- The assertion is correct because nitro and nitrito indeed can coordinate through different atoms (N or O), making them ambidentate.
- The reason is also correct because the ability of these ligands to bind through different atoms leads to the formation of linkage isomers.

### Step 4: Conclusion
Both the assertion and reason are correct, and the reason provided is a valid explanation for the assertion. Therefore, the correct answer is that both the assertion and reason are true, and the reason explains the assertion.

### Final Answer
Both the assertion and the reason are correct, and the reason is the correct explanation of the assertion.
