`SF_(4)` is obtained by treating sulphur with

Options

A. `F_(2)`
B. `CoF_(2)`
C. `CoF_(3)`
D. `CoF_(6)^(3-)`

Answer

To solve the question of how SF₄ (sulfur tetrafluoride) is obtained, we can follow these steps:

### Step 1: Identify the reactants
We need to determine what sulfur is treated with to produce SF₄. According to the video transcript, sulfur is treated with COF₃ (carbon oxyfluoride).

### Step 2: Write the reaction
The chemical reaction can be represented as:
\[ \text{S} + \text{COF}_3 \rightarrow \text{SF}_4 + \text{COF}_2 \]

### Step 3: Analyze the products
In this reaction, sulfur (S) reacts with COF₃ to produce sulfur tetrafluoride (SF₄) and carbon oxyfluoride (COF₂).

### Step 4: Conclusion
From the analysis, we conclude that SF₄ is obtained by treating sulfur with COF₃.

### Final Answer
SF₄ is obtained by treating sulfur with COF₃.
