H2S is the group Reagent
the separation of insoluble precipitated with the treatment of various precipitant called group reagent
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.
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.
This reagent is bromine in solution.
Borch's reagent, a mixture of sodium borohydride and iodine in methanol, is used for selective reduction of carboxylic acids to alcohols. It is a milder reagent compared to lithium aluminum hydride and provides higher chemoselectivity for carboxylic acid reduction.

Another reagent that can be used to precipitate cations of the silver group is hydrochloric acid (HCl).

Tollens' reagent is typically used to detect the presence of aldehydes but may not react with fructose due to its ketone functional group.
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.

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.
2[Ag(NH3)2]OH is tollen's reagent
In the synthesis of 2-bromobutane using NAI as the reagent, the reaction mechanism involves the substitution of a bromine atom for a hydroxyl group on butanol. This reaction follows an SN2 mechanism, where the nucleophile (bromine) attacks the carbon attached to the hydroxyl group, leading to the formation of 2-bromobutane.
Tollen's reagent is a test used to detect the presence of aldehydes, as it produces a silver mirror when it reacts with aldehydes, but not with ketones or other compounds. Baeyer's reagent is a solution of potassium permanganate (KMnO4) used to oxidize and distinguish between primary and secondary alcohols. Primary alcohols are oxidized by Baeyer's reagent to form carboxylic acids, while secondary alcohols are oxidized to form ketones.
The LAL reagent water can be sterile WFI or other water that show reaction with the specific LAL reagent with which it can be used, at the limit of the sensitivity of such reagent.
