Why acetoacetic ester gives ferric chloride test?

Acetoacetic ester gives a positive ferric chloride test due to the presence of the beta-keto group in the molecule. The keto group reacts with ferric chloride to form a colored complex, producing a characteristic color change that indicates the presence of the keto group in the compound.


Is vanillin positive in a ferric chloride test?

Yes, vanillin is positive in a ferric chloride test. When vanillin reacts with ferric chloride, it forms a colored complex that gives a characteristic blue or green color, indicating the presence of phenolic compounds.


What is the mechanism of ferric chloride test?

The ferric chloride test is used to detect the presence of phenolic compounds in a substance. It involves adding ferric chloride solution to the sample, and if phenolic compounds are present, a colored complex forms due to the formation of iron-phenol complexes. The intensity of the color change can be used to estimate the concentration of phenolic compounds in the sample.


Why would vanillin test positive in a ferric chloride test?

Vanillin contains aromatic groups that can form colored complexes with ferric chloride, resulting in a positive test by producing a color change. This reaction is commonly used to detect the presence of phenolic compounds like vanillin in a sample.


What is the function of ferric chloride in the detection of deaminase activity?

Ferric chloride is used in the detection of deaminase activity to detect the production of ammonia. When a deaminase enzyme acts on an amino acid to remove the amino group, ammonia is produced as a byproduct. The presence of ammonia can then be detected by forming a complex with ferric chloride, leading to a color change in the test solution.

Why normal ferric chloride is not used in detection of phenol?

Normal ferric chloride gives a positive test for phenol as it forms a violet complex with it. This can lead to false positives in other compounds that also react with ferric chloride, making it unreliable for detecting phenol specifically. Instead, a modified version called FeCl3/KI reagent is commonly used for phenol detection as it gives a distinct green color with phenol, allowing for more accurate and specific results.


What is the purpose of the ferric chloride test and how is it used in chemical analysis?

The purpose of the ferric chloride test is to detect the presence of phenols in a substance. In chemical analysis, ferric chloride is used as a reagent to react with phenols, producing a color change that indicates the presence of these compounds. This test is commonly used in organic chemistry to identify and quantify phenols in various samples.


How is a positive test for phenols using ferric chloride recognized?

A positive test for phenols using ferric chloride is recognized by the formation of a colored complex. When phenols react with ferric chloride, a deep purple or blue color indicates the presence of phenols. This color change occurs due to the formation of an iron-phenol complex.

Why ferric chloride test is not used to identify alcohols?

Because it's a test for phenols or enols. Please see the link.


What are two tests distinguish between ethanol and phenol?

The ferric chloride test: Ethanol does not react with ferric chloride, while phenol forms a purple color when mixed with ferric chloride. The bromine water test: Ethanol does not react with bromine water, while phenol decolorizes bromine water due to its reducing properties.


2 Why does aspirin not give a positive ferric chloride test as salicylic acid does?

Because aspirin does not contain OH group like salicyclic acid so ferric chloride preferes to react with a compounds that have OH group.

Why using phosphate buffer and magnesium sulphate and calcium chloride and ferric chloride for dilution water in BOD5 test?

Phosphate buffer helps maintain the pH of the dilution water, which is crucial for proper bacterial activity in the BOD5 test. Magnesium sulfate, calcium chloride, and ferric chloride provide essential nutrients for the bacteria to thrive and efficiently break down organic matter during the test. These chemicals help create an environment that supports the growth and metabolic activity of the microorganisms responsible for oxygen consumption in the BOD5 test.
