Identification of an organic compound Aim: To identify an unknown compound that has one oxygen atom per molecule, To establish the functional group of the compound, to prepare a derivative and find its melting point, and finally to determine the boiling pont of the original compound. Plan Establishing the functional group of the compound: To firstly determine the functional group I will carry out Diagnostic tests for functional groups, The test and positive observed reaction is shown below: Functional groupTestPositive resultCarbonylCollect some 2,4-dinitrophenylhydrazine (Brady's reagent) in a dry tube and add a very small amount of the compound and shake.A yellow or orange precipitate forms slowlyAldehydeCollect some silver nitrate solution. Add 2 drops of sodium hydroxide solution, then aqueous ammonia until the mixture is almost colorless. Now add a very small amount to the substance.A grey/black precipitate or silver mirror will be formedKetoneTake some iodine in potassium iodide solution; add sodium hydroxide until it...
