WebCommon Uses of Fehling’s Test. Some common uses of Fehling’s test are; it is used to determine whether a carbonyl group is an aldehyde or a ketone. Aldehydes tend to get oxidized and give positive result. Ketones apart from alpha-hydroxy-ketones do not react. Fehling’s test is also used as a general test for monosaccharides where a ... WebStep 2: Drop-wise addition of aqueous ammonia so that the precipitation of silver oxide entirely dissolves in the solution. The reagent will oxidize an aldehyde compound to its corresponding carboxylic acid. The reaction also reduces the silver ions present in the Tollen’s Reagent to metallic silver.

WebMonosaccharides. 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.
