2) You just been given an unknown organic liquid and told that it is either propanal, cyclohexanone, or butylamine. Name ONE chemical test("odor" is NOT a chemical test because it is much too subjective) you could perform on the unknown to prove it was propanal, AND state what would you observe in that test to support your answer.
