Identification of an unknown organic compound

... Identification of an unknown organic I have been supplied with an unknown organic compound containing one of the following functional groups: * Alkene * primary alcohol * tertiary alcohol * aldehyde * ketone * carboxylic acid * ester * phenol By completing a series of chemical tests, the functional group can be established and therefore what the organic compound is. Complete the following tests in this order in accordance with the flowchart and safety procedures, to identify the functional group. 1. Test to identify a C=C bond We will start with the bromine test. This particular test identifies phenols and the presence of unsaturated C=C bonds found in alkenes. Equipment required: * Bromine water * Unknown organic * Pipette * Test tube Procedure: Add the bromine water drop by drop to 1cm3 of the unknown compound a test tube and shake. Outcome for an alkene: The bromine water has a distinct orange/brown colour; an alkene will decolourise the bromine producing a clear liquid. Explanation: The C=C double bond
