Which of the following will produce red color when treated with `(NH_(4))_(2)[Ce(NO_(3))_(6)]`?

Options

A. `CH_(3)OH`
B.
C.
D. `PhOH`

Explanation

To solve the question, we need to determine which substances will produce a red color when treated with ammonium cerium nitrate, `(NH₄)₂[Ce(NO₃)₆]`.

### Step-by-Step Solution:

1. **Understanding the Reaction**:
- Ammonium cerium nitrate is known to form colored complexes with various organic compounds. The color produced depends on the nature of the organic compound used.

2. **Identifying the Compounds**:
- The question likely provides a list of compounds (not specified here). However, we will consider common examples such as methanol, phenol, and others.

3. **Testing Methanol**:
- When methanol is treated with ammonium cerium nitrate, it forms a red-colored complex. This is due to the interaction between the cerium ions and the hydroxyl group in methanol, leading to a specific electronic transition that results in the red color.

4. **Testing Phenol**:
- On the other hand, when phenol is treated with ammonium cerium nitrate, it produces a brown-colored complex. This indicates that phenol does not produce the red color we are looking for.

5. **Conclusion**:
- Based on the information provided, methanol is the compound that produces a red color when treated with `(NH₄)₂[Ce(NO₃)₆]`. Other compounds may vary in their results, but phenol does not produce red.

### Final Answer:
- The compound that will produce a red color when treated with `(NH₄)₂[Ce(NO₃)₆]` is **methanol**.
