A : `XeF_(6)` on the reaction with RbF gives `Rb[XeF_(7)]`
R : `XeF_(6)` is non - reactive .

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion , then mark (1)
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion , then mark (2)
C. If Assertion is true statement but Reason is false , then mark (3)
D. If both Assertion and Reason are false statements , then mark (4)

Answer

To analyze the given assertion and reason, we will break down the information step by step.

### Step 1: Understanding the Assertion
The assertion states that `XeF_(6)` reacts with `RbF` to produce `Rb[XeF_(7)]`.

- **Explanation**:
- `XeF_(6)` is a known compound of xenon.
- When it reacts with rubidium fluoride (`RbF`), it forms a complex ion `Rb[XeF_(7)]`.
- This reaction involves the addition of an extra fluoride ion to the xenon, resulting in the formation of `XeF_(7)`, which is a valid complex.

### Step 2: Evaluating the Reason
The reason states that `XeF_(6)` is non-reactive.

- **Explanation**:
- While it is true that `XeF_(6)` has a stable octet and can be considered relatively stable, it is not entirely non-reactive.
- The fact that it can react with `RbF` to form `Rb[XeF_(7)]` indicates that it does have the ability to undergo reactions under certain conditions.

### Step 3: Conclusion
- **Assertion**: True (since `XeF_(6)` does react with `RbF` to form `Rb[XeF_(7)]`).
- **Reason**: False (since `XeF_(6)` is reactive in this context).

### Final Answer
- The assertion is true, but the reason is false. Therefore, the correct option is that the assertion is correct and the reason is incorrect.
