Lab Nitration of an aromatic compound Objective This experiment will be a nitration of a monosubstituted aromatic compound. The compound will be a meta, ortho or para director The purpose of the experiment is to synthesize an aromatic nitration product and characterize it Chemical Equation ΗΝΟ, H, SO. 0 °C NO2 Unknown

C) CN + CI 80% Draw the mechanism for this reaction and comment on the need for the promoter AlCl. (15) Explain why the para-substituted product F was formed selectively in this reaction. Include in your answer an analysis of the stabilisation of the cationic intermediates in the pathways leading to both the meta and para products. (15) Briefly explain why no disubstitution products were observed in this reaction.

Question 3
1s 3 ORTHO Today we learned about adding a second group to a mono-substituted benzene ring. Any group on a benzene will affect the rate of the reaction (activated or deactivated relative to benzene) and the regioselectivity Where does the electrophile add? Ortho? Meta? Para? Some combination thereof? We found that EDGs (electron-donating groups) direct the electrophile to the ortho and para positions while EWGs (electron-withdrawing groups) direct the electrophile to the meta position. Now, it is time...

Add the following questions to the final report: a) Why does the carbomethoxy group directs the reaction to positions that are meta to it? b) Why the formation of dinitrobenzaote is substantially disfavored ? c) Would you expect small amounts of the ortho and para substituted product? How would you remove them if they are formed ? d) Why does water have a retarding effect on the nitration ? e) Explain why Benzene has lower reactivity in electrophilic addition reactions...
