3. Propose a structure corresponding to the spectral data which are provided. CsH8N203. Put your final answer in the box. Hint: The proton at 10.3 ppm is NOT what you would suspect at that region. There are two coupling constants given for the triplets around 7-8 ppm because they are really distorted doublets of doublets. Explain your answer to receive full credit. Based on your answer you can assign a structure to problem 9 in Part I which is isomeric....
