I. Full Spectral Problems. Compound A (nominal MW =121amu ) provides the spectral data below (only IR and MS data are shown fully, while NMR data are reported as line lists and tabulated in the answer sheets for you to write interpretations directly onto). Fill out the tables below and provide full spectral analysis to determine the structure of compound A. Furthermore, answer the additional questions that ensue. Show full solutions, interpretations and partial structures or fragments in the provided answer sheets. Print and write all your answers directly onto these sheets. (20+5) Compound A: 'H NMR (90 MHz, CDCl3)δH7.50−7.10(5H,m),3.74(2H,s),2.43(3H,s),2.20(1H, broad s) 13C NMR (25 MHz,CDCl3)δC140.3,128.3,128.1,126.9,56.1,36.0
