• Comment on the reactivity of N-methylmaleimide specifically why it is such a reactive dienophile. . ● Comment on the reactivity of 9-anthracenemethanol specifically why it is such an unreactive diene. As the reaction proceeds, the TLC analysis shows a reduction in fluorescence in going from the 9-anthracenemethanol starting material (fluorescent) to the cycloaddition product (non- fluorescent). Explain this observation.

Can you answer this question regarding this procedure: Discuss how bromobutane was made (the mechanism) and then how it was purified. Discuss success of the reaction in terms of yield and purity. Based on the mechanism, do you expect this to be a high yielding reaction? Why/why not? What could be changed (if anything) about the way the reaction was performed to increase the yield? Was the product isolated pure (discuss the IR)? Why was the product isolated the way that it was (what was the point of the different wash steps) and could it have been purified another way? Did the purification method cause significant loss of product (impacting the yield)? and if so, what could be done to prevent that in the future?
