Tollens' reagent is a chemical reagent used to distinguish between aldehydes and ketones along with some alpha-hydroxy ketones which can tautomerize into aldehydes. The reagent consists of a solution

…Liebig improved it in 1856. The process was further refined and made easier by the chemist Tony Petitjean (1856). This reaction is a variation of the Tollens' reagent for aldehydes. A solution of diamminesilver(I) is mixed with a sugar and sprayed onto the glass surface. Silver(I) oxidizes the sugar, reducing itself…
