Pаrt II: There аre FOUR Questiоns fоr this pаrt оf the exam. READ CAREFULLY below about how to submit your answers: 1) Write your answer for each question on plain sheet(s) of paper. 2) Write the Question number, Indicate your answers clearly, and Draw a horizontal line to separate each question. 3) Show your answers to the webcam when you have completed all questions. 4) Click "Submit Button" on this page (below) when you are ready to turn in. This will also close Honorlock. 5) Scan or take picture of your Part II written answers. 6) Generate a submittable SINGLE PDF file. 7) Upload your PDF file on the Module 5 Exam-Part II submission link in this Module on Canvas. Make sure that your images are oriented correctly, not upside down or turn sideways. Each image must be clear and legible or your exam will not be graded, which will result in 0 point on the exam. Part II: Question 1 (12 points) This question has THREE parts: From the following Electrocyclic Ring Closure reaction: Problem viewing the image, Click Preview Here 1.1) How many electrons are involved in the reaction? (2 points) 1.2) Will the ALLOWED reaction as shown above proceed via a Huckel or a Mobius transition state? (5 points) 1.3) Will the ALLOWED reaction as shown above proceed via conrotatory or disrotatory ring closure? (5 points) Part II: Question 2 (25 points) This question has TWO parts: From the following reaction, Problem viewing the image, Click Preview Here 2.1) Draw the the step-by-step curved arrow pushing mechanism to show the formation of the carbocation electrophile starting from the reaction between alcohol and acid (H-Cl) given to you below. (5 points) Problem viewing the image, Click Preview Here 2.2) Draw the step-by-step curved arrow pushing Electrophilic Aromatic Substitution mechanism to show the formation of the major final product starting from the reaction between benzene and the specific carbocation electrophile from Part I. Use Cl– as the base in the last proton transfer step. Lone pair electrons and ALL related resonance contributors of the sigma complex must be included in your drawing. (20 points) Part II: Question 3 (28 points) Provide a multi-step synthesis of the target structure on the right from the starting structure on the left. Indicate the reagents/conditions and the major organic products at each step, do not show any curved-arrow pushing mechanisms.
