Q. Tollen's test can be used to distinguish

J & K CETJ & K CET 2012Aldehydes Ketones and Carboxylic Acids

Solution:

Tollen's test is used to distinguish between propionaldehyde and acetone because Tollen's reagent is a weak oxidising agent and results in the formation of silver mirror with aldehydes. The test is only shown by aldehydes and not by ketones.
