Question
**Question 2: Explanation for a Negative Iron(III) Test with Eugenol** Eugenol is a naturally occurring compound often used in the fragrance and flavoring industries. When performing an iron(III) chloride test, it typically results in a color change indicating the presence of phenolic compounds. A negative result, meaning no significant color change, suggests the absence or insufficiency of such compounds in the test sample, or that the sample contains interfering substances. Additionally, consider whether the test was conducted under appropriate conditions regarding concentration and pH, which can affect the outcome.
