On the аnswer sheet prоvided tо yоu for the exаm, or on scrаp paper, complete the following question: Written Response Question 1 (12 pts): Complete the following chemical reaction showing all major organic products; illustrate proper stereochemistry where appropriate. If no reaction occurs, indicate “NR”. Click to Show Image Description A central benzene ring with three alternating double bonds bears a CH₃ group at the top and an NH₂ group at the opposite, lower carbon. Four reaction arrows extend outward from this structure. The upper-left arrow lists 1) NaNO₂/HCl and 2) Cu₂O, H₂O. The upper-right arrow lists 1) NaNO₂/HCl and 2) NaI. The lower-left arrow is labeled H₂SO₄, Δ. The lower-right arrow shows CH₃CH₂CH₂Cl above the arrow and AlCl₃ below it. No product structures are shown.
On the аnswer sheet prоvided tо yоu for the exаm, or on scrаp paper, complete the following question: Written Response Question 11 (3 pts): Synthesize the following compound from benzene. Show all steps as individual reactions (i.e. don’t pile up all the steps over one arrow.) Click to Show Image Description A six-membered benzene ring contains three alternating double bonds. A bromine atom labeled Br is bonded to the upper-left ring carbon, and an NH₂ group is bonded to the upper-right ring carbon. One unsubstituted ring carbon lies between the two attachment points along the top of the ring. No lone pairs are shown.

Show all steps as individual reactions (i.e. don’t pile up all the steps over one arrow.) Click to Show Image Description A six-membered benzene ring contains three alternating double bonds. An NH₂ group is attached to the lower-left ring carbon. A CH(Br)CH₃ group is attached to the opposite, upper-right ring carbon, with Br extending upward and CH₃ extending to the right. No lone pairs are shown.
