Perform the following organic analysis tests and functional group present: • the production of an orange/red precipitate with Fehling’s reagent to indicate the presence of the aldehyde functional group the production of a silver mirror/black precipitate with Tollens’ reagent to indicate the presence of the aldehyde functional group • the production of a yellow precipitate with alkaline aqueous iodine to indicate the presence of the CH3CO or CH3CH(OH) group • the change in colour of acidified potassium manganate (VIl) from purple to colourless to indicate the presence of a compound that can be oxidized.
