Observation Exercise Based On Organic Chemistry

... OBSERVATION EXERCISE BASED ON ORGANIC CHEMISTRY: You are provided with three organic compounds H, I and J. H, I and J each belong to different homologous series. Carry out the reactions below and record your observations. In each case make what deductions you can about the functional group in the compound under test. 1.In a fume cupboard. Lace 3 drops of H on a piece of broken pot or a crucible lid and try to ignite it with a wooden splint. Observation Inference The splint ignites, and all of H is burned, leaving no excess liquid, but a yellow mark no the crucible lid. There are double bonds present, which shows that solution H is unsaturated therefore H could be an alkene. 2.Place 1cm3 of H in a test tube, add equal volume of bromine water, cork the tube and shake the mixture. Observation Inference There was a colour change from orange to yellow, decolourisation. There was a layer of
