What substance is present in FeCl3 that gives a purple color?
Quite many compounds. Phenols are one of the most common group of compounds here. In other words: any compounds containing benzene ring connected to OH group will give you purple color when treated with FeCl3. It seems that if you have FeCL3 sample it is probably impurified by phenolic compounds.
What are the organic compounds that have an -OH functional group?
Alcohols and phenols (hydroxyl functional group)
Which compounds react with iron III chloride to give color change?
phenols
Is there bromine water discoloration at reaction with aqueous solution?
The bromine test (discoloration) is valid for compounds with double or triple bonds between carbon atoms and for phenols. This is a simple and common experiment.
What is the reaction mechanism of the folin ciocalteu reagent and poly phenols?
The Folin-Ciocalteu reagent which is a mixture of tungstates and molybdates works on the mechanism of oxidation-reduction reaction. The method strongly relies on the reduction of the mixture heteropolyphosphotungsates-molybdates by the phenolic compound which results in the formation of blue coloure chromogen. The phenolic compounds react with Folin-Ciocalteu reagent only under basic conditions adjusted by sodium carbonate solution. Under Basic conditions it has been observed that the phenolic compound undergoes dissociation to form a phenolate anion which reduces the Folin-Ciocalteu reagent i.e. the mixture of tungstates and molybdates rendering a blue coloured solution. The colour intensity of the formed blue chromogen can be measured by the absorbance readings using a spectrophotometer
What are the drugs containing phenols and phenolic derivatives?
Pramocaine , Dyclonine, Ketobemidone etc

What is the difference between alcohol and phenols?
Alcohol: C6H13OH (hydroxy-hexane) Phenol : C6H5OH (hydroxy-benzene) Phenolic -OH is acidic (4x stronger than vinegar) where s alcoholic -OH isn't acidic at all; both are NOT ionic or alkaline (OH-)
What are the organic compounds that have an -OH functional group?
Alcohols and phenols (hydroxyl functional group)
Which compounds react with iron III chloride to give color change?
phenols
What is an alkylphenol?
An alkylphenol is any of a family of organic compounds obatained by the alkylation of phenols.
Are isoflavones are phenols?
Isoflavones and phenols are both present in soybeans. Phenols are the basic building block of many plant constituents; many different phenolic compounds exist that are based on it. One such compound is salicylic acid, which is often combined with a sugar to form glycoside that is antiseptic. Saponins are glycosides. The steroidal saponins mimic the precursers of female sex hormones, and the tri-terpenoid saponins mimic the adrenal hormone ACTH. Saponins are present in small amounts in soybeans. Isoflavones are very similar in structure to estrogen.

What is the difference between polyphenols and phenols?
A phenol is a benzene ring with an hydroxl (OH) group attached. A polyphenol is composed of many such phenols strung together. In terms of everyday life, this description doesn't mean much. A number of fruits and vegetables are being studied based on their polyphenol content, as it's thought that these polyphenols may be responsible for the beneficial effects of these products. Pomegranates and grapes (especially in red wine) are known to be high in polyphenols. Eat your fruits and vegetables.
Is there bromine water discoloration at reaction with aqueous solution?
The bromine test (discoloration) is valid for compounds with double or triple bonds between carbon atoms and for phenols. This is a simple and common experiment.
