Hydrolysis of benzene sulphonic acid with super heated steam gives

Options

A. Benzene
B. Phenol
C. Nitrobenzene
D. Benzoic acid

Answer

To solve the question regarding the hydrolysis of benzene sulfonic acid with superheated steam, we can follow these steps:

### Step 1: Identify the Reactant
The reactant in this reaction is benzene sulfonic acid, which has the chemical formula C₆H₅SO₃H. It consists of a benzene ring (C₆H₅) attached to a sulfonic acid group (SO₃H).

### Step 2: Understand the Hydrolysis Process
Hydrolysis refers to the chemical breakdown of a compound due to reaction with water. In this case, benzene sulfonic acid reacts with superheated steam (which is water in gaseous form at high temperatures).

### Step 3: Write the Reaction
When benzene sulfonic acid is treated with superheated steam, it undergoes hydrolysis. The reaction can be represented as follows:

\[ \text{C}_6\text{H}_5\text{SO}_3\text{H} + \text{H}_2\text{O} \xrightarrow{\text{superheated steam}} \text{C}_6\text{H}_6 + \text{H}_2\text{SO}_4 \]

### Step 4: Identify the Products
From the reaction, we can see that the products formed are:
1. Benzene (C₆H₆)
2. Sulfuric acid (H₂SO₄)

### Conclusion
Thus, the hydrolysis of benzene sulfonic acid with superheated steam yields benzene and sulfuric acid.

### Final Answer
Hydrolysis of benzene sulfonic acid with superheated steam gives benzene (C₆H₆) and sulfuric acid (H₂SO₄).
