Vedclass · Answer

(A) The silver mirror test,also known as the $Tollens'$ test,is a chemical test used to distinguish between aldehydes and ketones. Aldehydes are oxidized to carboxylic acids by $Tollens'$ reagent,which is an ammoniacal silver nitrate solution,while the silver ions are reduced to metallic silver,forming a silver mirror on the inner surface of the reaction vessel. Ketones do not give this test.
