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.
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.
Why FeCl2 is not used to identify phenol?
Because it's a test for phenols or enols
Why ferric chloride test is not used to identify alcohols?
Because it's a test for phenols or enols. Please see the link.
Why do phenols alter pH?
Phenols have a low acidity.

Does Canadian bacon contain phenols?
Only if it's smoked - pork is naturally free from phenols, but the smoking process adds them.
Is there bromine water discoloration at reaction with aqueous solution?
Bromine water will change color in the presence of certain organic compounds, such as alkenes or phenols. When bromine water is added to an aqueous solution containing these compounds, the bromine will react with the double bonds in the alkenes or the aromatic rings in phenols, resulting in a color change from orange to colorless.
What is the chemical equation between phenol and ferric chloride?
We use Ferric Chloride (FeCl3) in the lab to test for the presence (or in some case absence) of phenols, although some enols will also yield positive results. The OH (hydroxy group) which is attached directly to an aromatic nucleus (Benzene, for example) is detected by the Ferric chloride. It is important to note that alcohols do not undergo the reaction. Phenols will typically yield dramatic purple,blue,red or green color as an indication of a positive test. FeCl3 will also indicate the presence of aliphatic acids (that is, non-aromatic organic acids, such as Acetic acid) turning the solution a yellow color. Aromatic acids will test as a beige-tan color. Enols will also show a characteristic yellow color. It is also important to understand that not all phenols will test positively in the presence of the FeCl3 reagent. A good example of this is in highly hindered phenols which do not yield positive tests. However, a negative test is not completely conclusive, so other tests can be preformed to verify the absence of a phenol (such as NMR and IR spectroscopy) We use Ferric Chloride (FeCl3) in the lab to test for the presence (or in some case absence) of phenols, although some enols will also yield positive results.

What are the types of phenols found in industrial wastewater?
Types of phenols found in industrial wastewater include cresols, pentachlorophenol, bisphenol A, and chlorophenols. These compounds can be toxic to aquatic life and can cause environmental damage if released untreated into water bodies.
