Q.
Benzaldehyde and acetone can be best distinguished using
KCETKCET 2010Aldehydes Ketones and Carboxylic Acids
Solution:
With Fehling's solution, benzaldehyde as well as acetone do not react while with Tollen's reagent, benzaldehyde gives precipitate but acetone does not react. Hence, Tollen's reagent is used to distinguish them.
