Phenol Test
Easychemistry
Phenol reacts with FeCl₃ to give:
Select the correct option:
Solution
Incorrect! Answer:
Violet coloration
A characteristic test for identifying phenols and enols is the reaction with neutral Ferric chloride (FeCl3).
- Observation: A violet, blue, or green coloration is produced.
- Chemical basis: Formation of a colored coordination complex between the phenoxide ion and the Fe3+ center.
- Most aliphatic alcohols do not show this reaction, making it an excellent diagnostic tool for phenolic compounds in organic analysis.
