Aldehydes have at least one hydrogen attached to the carbonyl carbon; in ketones, no hydrogens are directly attached to the carbonyl carbon, only carbon containing R-groups: Learning objective: Identify aldehydic and ketonic functional groups in organic compounds by performing 2,4-dinitrophenylhydrazine test. In general, qualitative tests have some apparent visual change indicating when a reaction has occurred. Tollens’ reagent is a colorless, basic, aqueous solution containing silver ions coordinated to ammonia [Ag(NH3)2+][Ag(NH3)2+].

Tollen's reagent 3. Basic understanding of basic high school or college chemistry assumed (although there is some review). The initial and final observations for ketones have been completed. It details the … When butanal is tested, what do you observe during the positive test for ketones and aldehydes? When hexane is tested, what do you observe during the negative test for ketones and aldehydes? The name silver-mirror test arises because this reaction produces a precipitate of silver, whose presence can be used to test for the presence of an aldehyde. 4.
