Quizplus · Accepted Answer

Tollen's reagent is used to distinguish aldehydes from ketones and other functional groups. When an aldehyde is present, it gets oxidized, and the Tollen's reagent (ammoniacal silver nitrate) is reduced to metallic silver, which deposits on the container's walls, creating a silver mirror. This reaction does not occur with ethers, phenols, or ketones under these conditions.
