Assertion: In `N_(2)` Molecule, any N-atom can coordinate with central atom/ion.
Reason: `N_(2)` molecule can also act as ambidentate ligand.

Options

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

Answer

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

### Step 1: Analyze the Assertion
The assertion states that in the \(N_2\) molecule, any nitrogen atom can coordinate with a central atom or ion.

- **Explanation**: The \(N_2\) molecule consists of two nitrogen atoms connected by a triple bond. Each nitrogen atom has a lone pair of electrons. In coordination chemistry, a ligand is a species that can donate a pair of electrons to a central atom or ion. Since both nitrogen atoms in \(N_2\) have lone pairs, either nitrogen can act as a donor and coordinate with a central atom.

### Conclusion for Step 1:
The assertion is **correct** because both nitrogen atoms in \(N_2\) can coordinate with a central atom due to the presence of lone pairs.

---

### Step 2: Analyze the Reason
The reason states that the \(N_2\) molecule can also act as an ambidentate ligand.

- **Explanation**: An ambidentate ligand is one that can coordinate to a central atom through two different atoms. For example, in the case of the cyanide ion (\(CN^-\)), both carbon and nitrogen can act as donor atoms. However, in the case of \(N_2\), both donor atoms are the same (nitrogen), and there are no different atoms that can donate lone pairs. Therefore, \(N_2\) does not qualify as an ambidentate ligand.

### Conclusion for Step 2:
The reason is **incorrect** because \(N_2\) does not have two different donor atoms; it only has two identical nitrogen atoms.

---

### Final Conclusion:
- The assertion is correct.
- The reason is incorrect.
