What is the full arrow pushing mechanism for the following transformation? Hint: Remember, show all steps to convert the starting material into the product. Do not skip steps for full credit. You have to show how ALL bonds are breaking and forming for this transformation to occur. What is the full arrow pushing mechanism for the following transformation? Hint: Remember, show all steps to convert the starting material into the product. Do not skip steps for full credit. You have...
3. Draw the arrow-pushing mechanism of the reaction, including all proton transfer steps. 4. Below is the structure of your product, benzocaine, with protons labelled A-E. The 'H NMR spectrum is provided on the next page. Describe the multiplicity (with J values) and integration you would expect to observe for each of the protons. Which peak would you expect to have a higher chemical shift, C or D? Draw resonance OSO structures of benzocaine to explain your reasoning. NH2E
