Which of the following will give characteristic colour with `FeCl_(3)`

Options

A.
B.
C.
D.

Explanation

To determine which of the given compounds will give a characteristic color with FeCl₃, we need to analyze the options provided and their chemical nature.

### Step-by-Step Solution:

1. **Understanding the Reaction with FeCl₃**:
- Ferric chloride (FeCl₃) is known to react with phenolic compounds to form colored complexes. The most common color observed is violet.

2. **Identifying the Compounds**:
- We need to identify which of the given options are phenols or enols, as these are the compounds that will react with FeCl₃ to produce a color.

3. **Analyzing Each Option**:
- **Option 1**: Check if it is a phenol or enol. If it is not, it will not give a characteristic color with FeCl₃.
- **Option 2**: This is identified as a phenol. Since phenols react with FeCl₃ to give a violet color, this option is likely to be correct.
- **Option 3**: Similar to option 1, check if it is a phenol or enol. If it is not, it will not react with FeCl₃.
- **Option 4**: Again, check if it is a phenol or enol. If it is not, it will not give a characteristic color.

4. **Conclusion**:
- After analyzing the options, we find that **Option 2**, which is a phenol, will give a characteristic violet color with FeCl₃. The other options do not have the required functional groups to react with FeCl₃.

### Final Answer:
- The compound that will give a characteristic color with FeCl₃ is **Option 2** (the phenol).
