Aldehydes give a positive test – forms a silver mirror. Ketones give a negative test. Therefore, Propanal gives a positive test. Propanone gives a negative test. (ii) Acetophenone and Benzophenone Iodoform test – Methyl ketones give a positive iodoform test. WebTake a dry test tube and add the sample to it. Keep distilled water in another test tube as a control. Add the Fehling’s solution in both these test tubes. The tubes are recommended to be kept or held in water baths. Observations are to be made and any growth or development of red precipitate needs to be noted. tech free resorts
