Instructions The due date for this assignment is past. Your work can be viewed below, but no changes can be made. 1. 0.75/0.75 points Draw the major organic product formed with 1,2-dibromo-4-nitrobenzene reacts with sodium methoxide under heated conditions. Please review input instructions for the NO 2 group in the link below. COc1ccc([NO2])cc1Br Solution or Explanation The methoxide ion adds to (attacks) the carbon para to the nitro group which then quickly eliminates the bromide ion. 2. 0.75/0.75 points CH223 001 HW 35 http:[email protected]/student.pl?m=200812071. .. 1 of 9 12/7/2008 2:10 PM

Draw the major organic product formed from the reaction below when 1 equivalent of sodium methoxide is used. Hint: this one can be tricky if you do not consider other reactions that may compete with NAS. COCc1ccc([NO2])c(F)c1 Solution or Explanation S N 2 is a faster reaction than nucleophilic aromatic substitution because loss of aromaticiy is not a factor. 3. 2.5/2.5 points This question deals with nucleophilic aromatic substitution reactions in which the addition step is the rate determining step. The correction marks will not be shown for this question. I. Select the term that makes each of the following statements true.
