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.

Acetone does not react with Tollens' reagent (ammoniacal silver nitrate solution) because it does not contain an aldehyde group, which is necessary for the Tollens' test to occur. Tollens' reagent reacts with aldehydes to produce a silver mirror on the inner surface of the test tube.

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?

The reaction between sucrose and Tollens' reagent results in the formation of a silver mirror. The equation for this reaction is: C12H22O11 (sucrose) + 2Ag(NH3)2OH (Tollens' reagent) → 12Ag (s) + CO2 (g) + H2O (l) + 22NH3 (aq)


What is the equation for the reaction between tollens' reagent and butanone?

The reaction between Tollens' reagent (Ag(NH3)2+) and butanone forms a silver mirror on the inner surface of the reaction vessel. The equation for this reaction is: Ag(NH3)2+ (aq) + 2e- -> Ag(s) + 2NH3(aq)


What reaction occurs when benzil gives tollens test?

Benzil does not react with Tollens reagent because it does not contain aldehyde or ketone functional groups. Tollens reagent is a silver mirror test used for the detection of aldehydes in a sample by the reduction of silver ions to metallic silver. Benzil, being a diketone, does not undergo this reaction.


Why Tollens reagent does not react with ketone?

Tollens reagent is a mild oxidizing agent that reacts with aldehydes to produce a silver mirror. Ketones, however, do not have a hydrogen atom bonded to the carbonyl group, making them resistant to oxidation by Tollens reagent. As a result, ketones do not react with Tollens reagent.


Does tollens reagent react with cyclohexanone?

Yes, Tollens' reagent can react with cyclohexanone. Tollens' reagent is commonly used to test for the presence of aldehydes, including cyclohexanone, by forming a silver mirror when the aldehyde is present.


Is fructose gives positive test with tollens reagent?

Fructose does not give a positive test with Tollens' reagent because it is a reducing sugar that does not have a free aldehyde group capable of reducing the Tollens' reagent. Tollens' reagent is typically used to detect the presence of aldehydes but may not react with fructose due to its ketone functional group.


Equation for the reaction of ethanal with Tollens reagent?

The reaction of ethanal with Tollens reagent results in the formation of a silver mirror. The chemical equation for this reaction is: 2 Ag(NH3)2+ + RCHO + 5 OH- → 2 Ag + RCOO- + 4 NH3 + 3 H2O


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.


Why can't you prepare and store tollens' reagent in advance for tests?

Tollens' reagent is made by mixing two solutions - silver nitrate and ammonia - right before use because the reaction is sensitive to light, air, and temperature, which can degrade the reagent quickly. Preparing it in advance may lead to a loss of effectiveness, affecting the results of tests. Therefore, it is best to prepare Tollens' reagent fresh when needed for accurate testing.


What is formula of tollens reagent?

2[Ag(NH3)2]OH is tollen's reagent


What is the Formula for oxidation product formed from formaldehyde in the Tollens test?

The oxidation product formed from formaldehyde in the Tollens test is formic acid (HCOOH). The reaction involves the oxidation of formaldehyde by silver ions in the Tollens reagent to produce a silver mirror.
