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.
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.
What is the reaction of acetone and 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.
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.
Why ketone do not react with Fehlings solution and Tollens reagent?
Ketones do not react with Fehling's solution or Tollens' reagent because they lack the free aldehyde group necessary for these reactions to occur. Both Fehling's solution and Tollens' reagent depend on the presence of the aldehyde group to participate in redox reactions that lead to the formation of a colored precipitate. Without this aldehyde group, ketones do not undergo these reactions.
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.

Does the tollens test deal with alkenes?
No, the Tollen's Silver Mirror Test only confirms the presence of aldehydes.
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.

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.
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.
Why ketone do not react with Fehlings solution and Tollens reagent?
Ketones do not react with Fehling's solution or Tollens' reagent because they lack the free aldehyde group necessary for these reactions to occur. Both Fehling's solution and Tollens' reagent depend on the presence of the aldehyde group to participate in redox reactions that lead to the formation of a colored precipitate. Without this aldehyde group, ketones do not undergo these reactions.
What is the mechanism of the Tollens test and how does it differentiate between aldehydes and ketones?
The Tollens test involves the oxidation of aldehydes to carboxylic acids by silver ions in a basic solution. This forms a silver mirror on the inside of the test tube. Ketones do not react with Tollens reagent and do not produce a silver mirror. This test is used to differentiate between aldehydes and ketones based on their reactivity with Tollens reagent.

Equation for the reaction of ethanal with Tollens reagent?
Well, darling, the equation you're looking for is: CH3CHO + 2[Ag(NH3)2]+ + 3OH- → 2Ag + CH3COO- + 4NH3 + 2H2O. It's a fancy way of saying that ethanal reacts with Tollens reagent to form silver, acetate, ammonia, and water. So go ahead, impress your chemistry buddies with this little gem.
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.
