Which of the following halogen cannot from more than one oxoacids ?

Options

A. Bromine
B. Iodine
C. Fluorine
D. Chorine

Answer

To solve the question of which halogen cannot form more than one oxoacid, we will analyze the oxoacid formation capabilities of each halogen: fluorine, bromine, and iodine.

### Step-by-Step Solution:

1. **Understanding Oxoacids**:
Oxoacids are acids that contain oxygen, hydrogen, and another element (the central atom). For halogens, these are typically formed by combining the halogen with oxygen and hydrogen.

2. **Analyzing Fluorine**:
- Fluorine is the most electronegative element and has a small atomic size.
- It can only form one oxoacid: **Hypofluorous acid (HOF)**.
- Due to its high electronegativity, it does not form multiple oxoacids like other halogens.

3. **Analyzing Bromine**:
- Bromine can form multiple oxoacids, including:
- **Hypobromous acid (HBrO)**
- **Bromous acid (HBrO2)**
- **Bromic acid (HBrO3)**
- **Perbromic acid (HBrO4)**
- Thus, bromine can form more than one oxoacid.

4. **Analyzing Iodine**:
- Iodine can also form multiple oxoacids, such as:
- **Hypoiodous acid (HIO)**
- **Iodous acid (HIO2)**
- **Iodic acid (HIO3)**
- **Periodic acid (HIO4)**
- Therefore, iodine can also form more than one oxoacid.

5. **Conclusion**:
- After analyzing all three halogens, we find that **fluorine** is the only halogen that cannot form more than one oxoacid. The answer is **fluorine**.

### Final Answer:
Fluorine (Option C) cannot form more than one oxoacid.
