Formic acid reduces tollen's reagent
WebAns. Tests to distinguish between aldehydes and ketones: Tollens’ test: When an aldehyde is heated with Tollens’ reagent, it forms a silver mirror. Tollens’ reagent is an ammoniacal solution of AgNO 3. RCHO + 2 [Ag (NH3)2]+ + 3OH- → RCOO- + 2Ag + 2H2O + 4NH3. Ketones do not form a silver mirror. Fehling’s test: WebThe correct options are. B CH3COCH3. C Nitrobenzene. Tollen's test is given by those compounds which contain free aldehydic group as can be seen CH3COCH3 does not contain aldehydic group but it contains ketonic group, similarly Nitrobenzene contains nitro group (−N O2). Hence, option (c) and (b) does not reduce tollen's reagent.
