Vedclass · Answer

(A) Fehling's test is used to distinguish between aliphatic aldehydes and aromatic aldehydes or ketones. Aliphatic aldehydes,such as $CH_3CHO$ (Acetaldehyde),give a positive Fehling's test by forming a reddish-brown precipitate of $Cu_2O$. Benzaldehyde is an aromatic aldehyde and does not respond to Fehling's test. Ethers and alcohols do not contain the carbonyl group required for this oxidation reaction.
