Fehling's solution can be used to distinguishaldehyde vs ketone functional groups. The compound to be tested is added to the Fehling's solution and the mixture is heated. Aldehydes are oxidized, giving a positive result, but ketones do not react, unless they are α-hydroxy ketones. Which do...
As we've seen,glucose is in equilibrium with an open-chain (or “linear”) form containing an aldehyde. ... This means that glucose will give a positive test with Benedicts' reagent, Fehlings solution, or the Tollens test, and the aldehyde will be oxidized to a carboxylic acid. What i...
