Alkanals can be distinguished from alkanones by the reaction with
Answer Details
Alkanals and alkanones are both types of organic compounds that contain carbonyl functional groups. However, they can be distinguished from each other by their reaction with Tollens' reagent (also known as silver mirror test) or Fehling's solution. Alkanals are oxidized by Fehling's solution to form a brick-red precipitate of copper(I) oxide, while alkanones do not react with Fehling's solution. On the other hand, Tollens' reagent is used to distinguish between alkanals and alkanones by producing a silver mirror when it reacts with alkanals, but not with alkanones. Therefore, the correct answer to the question is Fehling's solution.
