B. `Cl_(2)`
C. `Br_(2)`
D. `I_(2)`

Answer

To solve the question "Which one of the following is not prepared from halide by chemical oxidation process?", we can follow these steps:

### Step 1: Understand the Concept of Halides and Oxidation
Halides are compounds derived from halogens (F, Cl, Br, I) when they react with metals. The oxidation process involves the loss of electrons, which can convert halides into their elemental forms.

**Hint:** Recall that oxidation is the process of losing electrons, while reduction is the gain of electrons.

### Step 2: Identify the Halogens and Their Properties
The halogens include fluorine (F), chlorine (Cl), bromine (Br), and iodine (I). Each halogen has different properties, particularly in terms of their electronegativity and reducing abilities.

**Hint:** Consider the trend in electronegativity and reducing properties of halogens as you move down the group in the periodic table.

### Step 3: Analyze the Reducing Properties
As we move down the group from fluorine to iodine, the reducing properties increase. Fluorine, being the most electronegative, has a very high standard reduction potential, which means it is a strong oxidizing agent.

**Hint:** Remember that a strong oxidizing agent cannot be oxidized further; it remains in its reduced form.

### Step 4: Evaluate the Oxidation of Halides
When considering the oxidation of halides to form their elemental forms, we need to determine which halides can be oxidized. For example:
- Chlorides (Cl-) can be oxidized to chlorine (Cl2).
- Bromides (Br-) can be oxidized to bromine (Br2).
- Iodides (I-) can be oxidized to iodine (I2).
- However, fluorides (F-) cannot be oxidized to fluorine (F2) because fluorine is already in its most oxidized state.

**Hint:** Think about whether each halide can be converted back to its elemental form through oxidation.

### Step 5: Conclusion
Based on the analysis, fluorine (F2) cannot be prepared from its halide (F-) through chemical oxidation because it is a strong oxidizing agent and cannot be oxidized further. Therefore, the correct answer to the question is F2.

**Final Answer:** F2 is not prepared from halide by chemical oxidation process.
