2. From the virtual observation, how will you know if a test has a positive result? Give example.3. Explain why for the confirmation of unsaturation in a compound, test with bromine water and testwith Bayer's reagent, should be performed.4. Why does benzene not decolorize bromine water although it is highly unsaturated?Conclusion / Generalizations: Virtual Experimentation:1. Bromine Test: https://www.youtube.com/watch?v=vBMGNzRYngkDissolve 0.1 g or 5 drops of organic compound in 2 mL of carbon tetrachloride in a test tube and add 2%solution of bromine in carbon tetrachloride or bromine water drop by drop with continuous shaking.Decolorization of bromine solution indicates the presence of unsaturation in organic compound.2. Baeyer's Test: https://www.youtube.com/watch?v=B1hqWTKXIQg&t=6sDissolve 25-30 mg of organic compound in 2 mL of water or acetone (free of alcohol) and add 1%potassium permanganate solution containing equal volume of 1% sodium carbonate solution. Thedischarge of the color of more than one drop of potassium permanganate indicates the presence ofunsaturation in the organic compound. Carrying out the reaction under alkaline conditions removes thepossibility of confusion due to substitution in aromatic compounds.3. Ceric Ammonium Nitrate Test: https://www.youtube.com/watch?v=6ik0Dzfpa18Take 1 mL solution of organic compound dissolved in a suitable solvent. Add a few drops of cericammonium nitrate solution. Appearance of red color shows the presence of alcoholic -OH group4. Ferric Chloride Test: https://www.youtube.com/watch?v=Xj0X3CS9J3kTake 2 mL of aqueous or alcoholic solution of the organic compound in a test tube, add neutralferric chloride solution dropwise and note the color change. Appearance of a blue, green, violet or redcolor indicates the presence of phenolic -OH group.

2) Colour Change 3) The double bond is brominated. 4) Benzene is aromatic in nature.
