What is the reagent used for group 2?
Group 2 reagents are used for the identification of cations such as calcium, strontium, and barium. Common reagents include ammonium carbonate, ammonium oxalate, and ammonium sulfate.
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.
What specific reagent precipitates the cations of group 2?
Ammonium carbonate ((NH4)2CO3) is a specific reagent that precipitates the cations of group 2 in qualitative analysis. It forms insoluble carbonates with cations such as calcium, strontium, and barium, allowing for their separation from other cations in the group.
What is the reagent that will convert benzaldehyde to benzoate ions?
The reagent that will convert benzaldehyde to benzoate ions is a base such as hydroxide ion (OH⁻) in the presence of water. The base deprotonates the aldehyde group of benzaldehyde to form the benzoate ion.
Would sucrose test positive or negative with benedicts reagent?
No, surcose is a disaccharide without a hemiacetal group

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.
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.
Another reagent that could be used in place of HCL to precipitate cations of the silver group?
Another reagent that can be used to precipitate cations of the silver group is hydrochloric acid (HCl).
What is the active ingredeint in sakaguchi reagent?
The Sakaguchi reagent consists of 1-Naphthol and a drop of sodium hypobromite. The guanidine group of arginine in proteins reacts with the Sakaguchi reagent.
What is the reagent that will convert benzaldehyde to benzoate ions?
The reagent that will convert benzaldehyde to benzoate ions is a base such as hydroxide ion (OH⁻) in the presence of water. The base deprotonates the aldehyde group of benzaldehyde to form the benzoate ion.
What is the mechanism of the reaction between lithium and a Grignard reagent, specifically focusing on the role of lithium in the formation of the Grignard reagent?
When lithium reacts with a Grignard reagent, it acts as a catalyst by initiating the formation of the Grignard reagent. The reaction involves the transfer of an alkyl or aryl group from the Grignard reagent to the lithium, resulting in the formation of a new carbon-carbon bond. This process is crucial for the synthesis of various organic compounds in organic chemistry.
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.
Would sucrose test positive or negative with benedicts reagent?
No, surcose is a disaccharide without a hemiacetal group
