Yes, it contains carbonyl functional group- aldehyde! :)
No.While vanillin is an aldehyde, which should react with Tollens' reagent to precipitate silver metal, vanillin does not "pass" Tollens' test. Tollens' reagent is very basic (sodium or potassium hydroxide). Vanillin has a phenolic hydrogen (OH bonded to a phenyl ring) which is slightly acidic. Vanillin will react first with the excess hydroxide ions in solution to form a phenoxide salt, which will not participate in the silver-precipitating reaction.
Yes, vanillin can give a positive iodoform test. The iodoform test is used to detect the presence of a methyl ketone group attached to a carbon atom adjacent to two other carbon atoms, and vanillin has a structure that can undergo this reaction.
Esters will not react with 2,4-dinitrophenylhydrazine (24-DNPH) because esters do not contain carbonyl groups (C=O) that are required for the reaction to occur. The reaction between 24-DNPH and carbonyl compounds such as aldehydes and ketones forms derivatives known as hydrazones, providing a useful test to identify these functional groups.
It has a C=O group attached to two R groups.
There are 14 hydrogen atoms in the vanillin molecule.
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.
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.

Vanillin is a single compound, not a mixture.
Because They Want It Taste Like Vanillin, They Want It Taste Chocolate And Vanillin At The Same Time.

A common substitute for Ninhydrin in the detection of amino acids and proteins is 2,4-dinitrophenylhydrazine (DNPH). DNPH reacts with carbonyl compounds to form hydrazones, which can be visualized through colorimetric methods. While Ninhydrin is primarily used for amino acids, DNPH is often utilized in the analysis of sugars and other carbonyl-containing compounds.
Reaction scheme of vanillin with potassium permanganate to vanillic acid...:)
Adderall will test positive for amphetamine. It is an amphetamine therefore it will test positive for such.
