Sulphuric acid reacts with `PCl_5` to give

Options

A. Thionyl chloride
B. Sulphur monochloride
C. Sulphuryl chloride
D. Sulphur tetrachloride

Explanation

To solve the question of what products are formed when sulfuric acid (H₂SO₄) reacts with phosphorus pentachloride (PCl₅), we can follow these steps:

### Step 1: Identify the Reactants
We start with two reactants:
- Sulfuric Acid (H₂SO₄)
- Phosphorus Pentachloride (PCl₅)

### Step 2: Write the Reaction
When sulfuric acid reacts with phosphorus pentachloride, the reaction can be represented as:
\[ \text{H}_2\text{SO}_4 + \text{PCl}_5 \rightarrow \text{SO}_2 + \text{Cl}_2 + \text{POCl}_3 + \text{HCl} \]

### Step 3: Identify the Products
From the reaction, we can identify the products formed:
- Sulfur Dioxide (SO₂)
- Chlorine Gas (Cl₂)
- Phosphoryl Chloride (POCl₃)
- Hydrochloric Acid (HCl)

### Step 4: Conclusion
The main product of interest in this reaction is sulfuryl chloride, which is formed along with other products. Therefore, the correct answer to the question is that sulfuric acid reacts with PCl₅ to give sulfuryl chloride.

### Final Answer
The products of the reaction between sulfuric acid and phosphorus pentachloride are:
- Sulfuryl Chloride (SO₂Cl₂)
- Phosphoryl Chloride (POCl₃)
- Hydrochloric Acid (HCl)
- Chlorine Gas (Cl₂)

Thus, the correct option is **C: Sulfuryl Chloride**.
