Step 1: Understanding the Question:
This question asks for the characteristic observation of the Ferric Chloride test, which is a specific qualitative test used to detect the presence of phenolic functional groups.
Step 2: Detailed Explanation:
When an aqueous or alcoholic solution of phenol is treated with a few drops of neutral ferric chloride (\(FeCl_3\)) solution, a complex coordination compound is formed.
The reaction can be represented as:
\[ 6C_6H_5OH + FeCl_3 \rightarrow [Fe(OC_6H_5)_6]^{3-} + 3H^+ + 3Cl^- \]
The formation of the iron-phenoxide complex results in a deep violet or purple coloration.
This test is used to distinguish phenols from alcohols, as simple alcohols do not react with neutral \(FeCl_3\) to produce such colors.
Step 3: Final Answer:
The color produced is violet.
