This reagent (2,4-dinitrophenylhydrazine) is used for Brady's test of carbonyl functionality. It adds to the aldehyde (or ketone) just like any other amination reaction to form a hydrazone. See the related link below.
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.
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.
Non-reducing sugars do not have a free aldehyde or ketone group, while reducing sugars do have a free aldehyde or ketone group that can react with other molecules.
No. It is an aldehyde. Furfural is furan-2-carboxaldehyde.
Cinnamaldehyde is an aldehyde. Its structure contains an aldehyde functional group (-CHO) attached to a benzene ring.
aldehyde is less stable than benzene so it react readily toward kmno4

Casein, a milk protein, does not typically give a positive aldehyde test. The aldehyde test is primarily used to identify aldehyde functional groups, which are not present in casein's structure. Instead, casein contains peptide bonds and amino acids, which do not react in the same way as aldehydes. Therefore, casein will not produce a characteristic reaction in an aldehyde test.

No. It is an aldehyde. Furfural is furan-2-carboxaldehyde.
Sucrose will not react with Benedict's solution. This is because sucrose is a non-reducing sugar, meaning it does not have a free aldehyde or ketone group that can be oxidized by Benedict's reagent.
Cinnamaldehyde is an aldehyde. Its structure contains an aldehyde functional group (-CHO) attached to a benzene ring.
Glucose is used for the preparation of Schiff base because it contains multiple hydroxyl groups that can react with an aldehyde or ketone to form a Schiff base. The reaction between glucose and the carbonyl compound leads to the formation of a stable imine or Schiff base linkage.
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.
An aldehyde oxidase is an enzyme which catalyzes the oxidation of an aldehyde to a carboxylic acid.
