CULMINATING ACTIVITY #2.....graded homework A hydrocarbon Z containing 4 carbons was mixed with aqueous chlorine and the pale yellow chlorine solution turned colourless to form compound R. When Z was mixed with hot concentrated acidified KMnO,, the purple solution turned brown; a gas was given off which turned limewater into a white precipitate. The remaining solution P turned Brady's reagent into an orange precipitate and Fehling's solution gave a red-orange precipitate What is the functional group in Z? i) ii) iii) iv) v) If HBr was added to Z .... • Draw the mechanism using curved arrow notation and • Name the end-product and the mechanism used. What process took place when Z was mixed with hot concentrated acidified KMnO4, was the process complete; cite reasons for your answer? ii) What is the identity (functional group) of P? Draw and name the displayed structures of P, Z and R. b) A manufacturer asked his laboratory chemist to use product R and create a Chlorofluorocarbon (CFC's) which would be used in an aerosol product being promoted by his company. i) Describe using equations, how you would do this....state any mechanisms which would be involved. List the advantages of using CFC's in aerosol cans. • Discuss the negative effect it would have one the environment and suggest a substitute for it.
