The oxoacid of sulphur that does not contain bond between sulphur atoms is:

Options

A. `H_(2)S_(2)O_(4)`
B. `H_(2)S_(2)O_(7)`
C. `H_(2)S_(2)O_(3)`
D. `H_(2)S_(4)O_(6)`

Explanation

To solve the question regarding which oxoacid of sulfur does not contain a bond between sulfur atoms, we will analyze the given oxoacids one by one.

### Step 1: Identify the oxoacids of sulfur
The oxoacids of sulfur we need to consider are:
1. H₂S₂O₄ (Thiodiphosphoric acid)
2. H₂S₂O₇ (Disulfuric acid)
3. H₂S₂O₃ (Thiosulfuric acid)
4. H₂S₄O₆ (Tetrathionic acid)

### Step 2: Analyze H₂S₂O₄
- **Structure**: H₂S₂O₄ has two sulfur atoms directly bonded to each other (S-S bond).
- **Conclusion**: Contains S-S bond. Not the answer.

### Step 3: Analyze H₂S₂O₇
- **Structure**: H₂S₂O₇ has two sulfur atoms, but they are connected through an oxygen atom (S-O-S bond).
- **Conclusion**: Does not contain a direct S-S bond. This could be the answer.

### Step 4: Analyze H₂S₂O₃
- **Structure**: H₂S₂O₃ has two sulfur atoms directly bonded to each other (S-S bond).
- **Conclusion**: Contains S-S bond. Not the answer.

### Step 5: Analyze H₂S₄O₆
- **Structure**: H₂S₄O₆ has four sulfur atoms in a chain, indicating multiple S-S bonds.
- **Conclusion**: Contains S-S bonds. Not the answer.

### Final Conclusion
After analyzing all the oxoacids of sulfur, the only oxoacid that does not contain a bond between sulfur atoms is **H₂S₂O₇**.
