List of organic compounds for analysis: . Benzaldehyde . Cinnamaldehyde . Acetophenone . Benzoic acid . Cinnamic acid . Urea . Glucose . Aniline . Salicylic acid organic organic - - - - .Charring test: When carbohydrates are treated with concentrated sulphuric acid, dehydration of carbohydrates results in charring. ∆ → H SO X y C H O x C + yH O . Ignition test Aromatic compounds burn with a strong sooty yellow flame because of the high carbon–hydrogen ratio. Aliphatic compounds burn with non-sooty flame. .Test with bromine water: In this test, the orange-red colour of bromine solution disappears when it is added to an unsaturated organic compound. . Test with KMnO (Baeyer’s Test ) In this test, pink colour of KMnO disappears, when alkaline KMnO is added to an unsaturated hydrocarbon. The disappearance of pink colour may take place with or without the formation of brown precipitate of MnO . C C unsaturated compound C C Colour less OH OH + H O + (O) 2KMnO + H O 2KOH + 2MnO + (O) . Neutral FeCl test: Phenol reacts with ferric ions to form violet coloured complex. Aqueous solution of naphthols do not give any characteristic colour with neutral ferric chloride. But alcoholic solution of α and β naphthols give blue-violet and green colouration respectively due to the formation of binaphthols. organic organic - - - - . Esterification test: Alcohols react with carboxylic acids to form fruity smelling compounds called esters. This esterification is catalysed by an acid such as concentrated sulphuric acid. + R C OH HO R' H SO ∆ R C R' + H O Carboxylic acid Alcohol Ester (pleasent fruity odour) . Tollen’s reagent test: Aldehydes react with Tollen’s reagent to form elemental silver, accumulated onto the inner surface of the test tube. Thus silver mirror is produced on the inner walls of the test tube. R-CHO Ag NH OH 2Ag Aldehyde Tollen'sreagent Meta
