Tollen's reagent is usually ammoniacal silver nitrate. Even in other variations it consists of an aqueous diaminesilver (I) complex. This diaminesilver (I) complex acts as an agent. This when placed in a test tube forms a silver mirror. Tollen's reagent is generally ammoniacal silver nitrate.
But it could be other reagents as well, as long as the complex diamminesilver(I) complex ion [Ag(NH3)2]+ can be generated.

It is usually ammoniacal silver nitrate, but can also be other mixtures, as long as aqueous diamminesilver(I) complex (or [Ag(NH3)2]+ cation) is present.

What is the equation for the reaction between tollens' reagent and butanone?
Does not react. Because Tollens' reagent only works with aldehydes. Butanone is methyl ethyl ketone (MEK).
Is fructose gives positive test with tollens reagent?
no negative
What is a reagent strip?
The reagent strip is a strip of paper impregnated with a specific chemical reagent for a chemical determination.
What compound can be oxidized by both Benedicts solution and Tollens reagent?
All the compounds having free aldehyde group as reducing sugars.
What is the molecular formula of schiff reagent?
C20H19N3·HCl
What is the reaction of acetone and tollens reagent?
Tollens' reagent is used to determine whether a carbonyl containing compound is an aldehyde or a ketone. Acetone is a ketone so it will not readily react with Tollens' reagent.
what is the outcome of tollens reagent reacting with methanal, ethanol and propanone?
The outcome of the Tollens reagent reacting with methanal (formaldehyde), ethanol (ethyl alcohol), and propanone (acetone) is the formation of metallic silver (Ag) in the case of methanal, while ethanol and propanone do not show a significant reaction with Tollens reagent. Tollens reagent is used as a chemical test to distinguish between aldehydes and ketones, where aldehydes react to produce a silver mirror, while ketones do not react.
What is the equation for sucrose and tollens reagent?

Why Tollens reagent does not react with ketone?
because
Does tollens reagent react with cyclohexanone?
yes!!
What are the components of tollens reagent?
tollen reagent
What is the equation for the reaction between tollens' reagent and butanone?
Does not react. Because Tollens' reagent only works with aldehydes. Butanone is methyl ethyl ketone (MEK).
Why pyrrole-2-aldehyde does not respond to tollens reagent?
Pyrrole-2-aldehyde does not respond to Tollens reagent because it is not a reducing sugar. Tollens reagent (silver nitrate) is used to test for the presence of aldehyde groups, which are commonly found in reducing sugars. Reducing sugars contain aldehyde groups and are capable of donating electrons to Tollens reagent, forming a silver mirror on the test tube wall. Pyrrole-2-aldehyde does not contain aldehyde groups, and therefore is not a reducing sugar. As a result, it does not react with Tollens reagent.
What is formula of tollens reagent?
2[Ag(NH3)2]OH is tollen's reagent
Is fructose gives positive test with tollens reagent?
no negative
Which reagent vanillin react?
vanillin violently reacts with Bromine in carbon tetrachloride,tollens reagent and aqueous NaOH
Is vanillin positive in tollens test?
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.
