Question

5. A given unknown has a singlet that resonates at 2.2 ppm and integrates to 3. Additionally a second singlet appears at 9.8 ppm and integrates to 1 on an H'NMR spectrum. What is the structure of the unknown? (5 points) 'Note: This problem can be solved with the above information, a f pay attention to chemical shifts and integrations!) 6. Provide the mechanism for the first step of the reaction below. The mechanism may be concluded after the addition of water (7 points). 1 Hg(OAc)2, H20 2. NaBH4 ?? + Enant
