Assertion (A) Linkage isomerism arises in coordination compounds containing ambidnetate ligand.
Reason (R) Ambidentate ligand has two different donor atoms.

Options

A. Assertion and reason both are true, reason is correct explanation of assertion.
B. Assertion and reason both are true but reason is not the correct explanation of assertion.
C. Assertion is true, reason is false.
D. Assertion is false, reason is true.

Explanation

To solve the question regarding the assertion and reason about linkage isomerism and ambidentate ligands, we can break it down into the following steps:

### Step 1: Understand the Assertion
The assertion states that "linkage isomerism arises in coordination compounds containing ambidentate ligands."

**Hint:** Linkage isomerism is a type of isomerism that occurs due to the different ways in which ligands can attach to the central metal atom.

### Step 2: Define Ambidentate Ligands
Ambidentate ligands are those that can bind to a metal ion through two different atoms. For example, the thiocyanate ion (SCN^-) can bind through sulfur (S) or nitrogen (N), making it ambidentate.

**Hint:** Identify examples of ambidentate ligands to understand how they can form different isomers.

### Step 3: Analyze the Reason
The reason states that "ambidentate ligands have two different donor atoms." This is true because the defining characteristic of ambidentate ligands is their ability to coordinate through different atoms.

**Hint:** Consider how the presence of two donor atoms allows for different binding arrangements.

### Step 4: Connect Assertion and Reason
Since the assertion claims that linkage isomerism arises due to ambidentate ligands, and the reason explains that these ligands have two different donor atoms, we can see that the reason supports the assertion.

**Hint:** Think about how the ability of a ligand to bind through different atoms leads to different structural arrangements.

### Step 5: Conclusion
Both the assertion and the reason are true, and the reason correctly explains why the assertion is true. Therefore, the correct answer is that both statements are true, and the reason is the correct explanation for the assertion.

**Final Answer:** Both the assertion and the reason are true, and the reason is the correct explanation for the assertion.
