On reacting with neutral ferric chloride, phenol gives

Options

A. red colour
B. blue colour
C. violet colour
D. green colour

Answer

To solve the question regarding the reaction of phenol with neutral ferric chloride, we can follow these steps:

### Step 1: Identify the Reactants
We start with phenol (C6H5OH) and neutral ferric chloride (FeCl3).

### Step 2: Understand the Reaction
When phenol reacts with ferric chloride, it forms a complex. This is a typical reaction where phenol acts as a ligand and coordinates with the iron ion (Fe³⁺) from ferric chloride.

### Step 3: Write the Reaction
The reaction can be represented as:
\[ \text{C}_6\text{H}_5\text{OH} + \text{FeCl}_3 \rightarrow \text{Fe(C}_6\text{H}_5\text{O)}_3 + 3\text{HCl} \]

Here, phenol forms a complex with Fe³⁺, resulting in the formation of a phenol-iron complex.

### Step 4: Identify the Product
The product formed is a phenol-iron complex, which is often represented as:
\[ \text{Fe(C}_6\text{H}_5\text{O)}_3 \]
This complex is known to impart a violet color to the solution.

### Step 5: Conclusion
Thus, the reaction of phenol with neutral ferric chloride results in the formation of a violet-colored complex.

### Final Answer
On reacting with neutral ferric chloride, phenol gives a violet-colored complex.
