Lesson 10
Identification Tests
Learning Intention: Evaluate how to identify different unknown organic molecules.
Success Criteria
6. I can identify “unlabelled” samples and justify that identification with equations.
A = Identified some
M = Identified most
E = Identified all with equations/creates a workable procedure to identify all of them
Learning Tasks
Watch the video showing how alkenes are identified with bromine water.
Complete the identification experiment with Ms Garlick. You will have three unknown samples, one that is an alcohol, one that is a carboxylic acid, one that is an amine. You will also be given water water (so you know what null looks like). With the following tests, you should be able to identify each one.
First do the dichromate and permanganate tests. You will need two test tubes 1-2 mL of each sample in a test tube. Make sure the test tubes are labelled 1, 2, and 3 to represent the samples and then W for the water one. For the first set, add a few drops of dichromate. With the second test, add a few drops of permanganate. The place into a beaker of hot water and observer which one changes colour.
For the next test, get a spotting tile. Label the column as 1, 2, 3, and W. In row one, rip a piece of red litmus to place on top. Second row, rip a piece of blue litmus. In the last row, add a few drops of sodium carbonate. Then, add the sample to it's column to note observations.

Teacher Notes
Removed for this year, but next year, add the organic vocab detective after task 1 so students can see the pattern with the groups and the functional groups.
