Fehling's solution

Vedclass · Answer

(B) Acetaldehyde is an aliphatic aldehyde,while benzaldehyde is an aromatic aldehyde.Fehling's solution is a mild oxidizing agent that can oxidize aliphatic aldehydes (like acetaldehyde) to their corresponding carboxylic acids,resulting in a red precipitate of cuprous oxide $(Cu_2O)$.However,aromatic aldehydes (like benzaldehyde) are not strong enough to be oxidized by Fehling's solution.Therefore,Fehling's solution can be used to distinguish between acetaldehyde and benzaldehyde.Tollen's reagent reacts with both aliphatic and aromatic aldehydes,so it cannot distinguish between them.
