Phenol gives . . . . . . . . Colour with neutral `FeCl_(3)` solution :

Options

A. violet
B. Green
C. Blue
D. Red

Answer

To determine the color that phenol gives with neutral FeCl₃ solution, we can follow these steps:

### Step 1: Understanding the Reaction
When phenol is added to neutral FeCl₃ solution, it forms a complex. This is due to the ability of phenol to donate a pair of electrons from its hydroxyl (-OH) group to the iron (Fe³⁺) ions present in the solution.

**Hint:** Consider how phenol interacts with metal ions and what type of complex might form.

### Step 2: Formation of the Complex
The reaction can be represented as:
\[ \text{Phenol} + \text{FeCl}_3 \rightarrow \text{Complex} \]
In this case, the phenol reacts with Fe³⁺ ions to form a phenol-iron complex.

**Hint:** Think about the charge of the iron ions and how they might interact with the phenol.

### Step 3: Identifying the Color of the Complex
The complex formed between phenol and Fe³⁺ ions is known to exhibit a characteristic color. Specifically, this complex typically shows a violet color.

**Hint:** Recall the common colors associated with metal complexes and how they can vary based on ligands.

### Step 4: Conclusion
Thus, when phenol is added to neutral FeCl₃ solution, it gives a violet color due to the formation of the phenol-iron complex.

**Final Answer:** Phenol gives a violet color with neutral FeCl₃ solution.
