Document Summary
Experiment 5 discussion questions: what is the mechanism of the reaction? (7 marks, explain, using theoretical background, the test for carbocation formation. Why is it yellow? (3 marks: the electrophilic substitution reaction of durene with excess br2 and febr3 catalysts are as depicted below. The reaction is complete in about one hour; all starting material is used up after 25 minutes. The bromine will only react with the most reactive compound before moving on to react further. Use relative spot sizes to indicate what is diminishing and what is being produced. Indicate which spots represent which compound. (hint: the febr3 will not move from the baseline) (10 marks: from the two reaction pathways below, draw the product each will produce. Discuss the differences in reactivity of each reagent. (5 marks: sources of error and references (5 marks)
