In organic chemistry, Fehling's solution is a chemical reagent used to differentiate between water-soluble carbohydrate and ketone (>C=O) functional groups, and as a test for reducing sugars and non-reducing sugars, supplementary to the Tollens' reagent test. The test was developed by German chemist Hermann von Fehling in 1849. [1]
The structure of the fuchsin dye. The Schiff test is an early organic chemistry named reaction developed by Hugo Schiff, [1] and is a relatively general chemical test for detection of many organic aldehydes that has also found use in the staining of biological tissues. [2]
Acetaldehyde is a common electrophile in organic synthesis. [31] In addition reactions acetaldehyde is prochiral. It is used primarily as a source of the "CH 3 C + H(OH)" synthon in aldol reactions and related condensation reactions. [32] Grignard reagents and organolithium compounds react with MeCHO to give hydroxyethyl derivatives. [33]
Tollens' test for aldehyde: left side positive (silver mirror), right side negative Ball-and-stick model of the diamminesilver(I) complex. Tollens' reagent (chemical formula ()) is a chemical reagent used to distinguish between aldehydes and ketones along with some alpha-hydroxy ketones which can tautomerize into aldehydes.
Aldehyde structure. In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) is an organic compound containing a functional group with the structure R−CH=O. [1] The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group.
