The reaction requires heating of aldehyde with Fehling's Reagent which will result in the formation of a reddish-brown colour precipitate. Hence, the reaction results in the formation of carboxylate anion. However, aromatic aldehydes do not react to Fehling's Test. Moreover, ketones do not undergo this reaction.
