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.
Practically glucose forms 2,4-diphenyl hydrazone on reacting with 2,4-dnp.
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.
Fehling's test is used to differentiate between aldehyde and ketones group. An aldehyde group will react with Fehling's reagent to give cuprous oxide resulting in a red precipitate. A Ketone group will not react with Fehling's reagent.
ethylene diamine metal complex react with aldehyde. will it form schiff base?
Tollens are chemical reagents that are commonly used to determine whether a known carbonyl containing compound is an aldehyde. It is stated that CH3CHO will not react to tollens at all.
cinnamaldehyde is a aldehyde hence cinnam(aldehyde)
aldehyde is less stable than benzene so it react readily toward kmno4

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.
No. It is an aldehyde. Furfural is furan-2-carboxaldehyde.
An aldehyde oxidase is an enzyme which catalyzes the oxidation of an aldehyde to a carboxylic acid.
I aldehyde dangerous to inhale
Answer:In two ways:1) If the aldehyde has alpha-hydrogen, you will get an aldol condensation, resulting in a beta-hydroxy aldehyde product.2) If the aldehyde does NOT have alpha-hydrogen, e.g. benzaldehyde, it will undergo a Cannizzaro reaction, in which it undergoes disproportionation to an alcohol and a carboxylic acid version of itself, respectively.
