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]
Hermann von Fehling was born in Lübeck.With the intention of taking up pharmacy he entered Heidelberg University about 1835. After graduating he went to Gießen as preparateur to Justus von Liebig, with whom he elucidated the composition of paraldehyde and metaldehyde.
Pyridinium dichromate (Cornforth reagent) converts primary and secondary alcohols to ketones Raney nickel: an alternative catalyst for the hydrogenation of vegetable oils; in organic synthesis, used for desulfurization Sakaguchi's Reagent: Detects the presence of arginine Samarium(II) iodide (Kagan Reagent) a powerful reducing agent Silver oxide
It is an ingredient of Fehling's solution (reagent for reducing sugars). It is used in electroplating, in electronics and piezoelectricity, and as a combustion accelerator in cigarette paper (similar to an oxidizer in pyrotechnics). [2]
Benedict's reagent (often called Benedict's qualitative solution or Benedict's solution) is a chemical reagent and complex mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate. [1] It is often used in place of Fehling's solution to detect the presence of reducing sugars and other reducing substances. [2]
In chemistry, a reagent (/ r i ˈ eɪ dʒ ən t / ree-AY-jənt) or analytical reagent is a substance or compound added to a system to cause a chemical reaction, or test if one occurs. [1] The terms reactant and reagent are often used interchangeably, but reactant specifies a substance consumed in the course of a chemical reaction. [ 1 ]
