An unknown compound was found to have the following spectral data: M+=206 and 208 in a 1:1 ratio. IR: 3000-2850 cm '; 1705 cm-1 IH NMR: 1.3 ppm (3H, t); 1.6 ppm (9H, s); 2.2 ppm (2H, q); 4.8 ppm (IH, S) 13C NMR: 6 total signals: 18 ppm, 21 ppm, 31 ppm, 39 ppm, 56 ppm, 190 ppm (3) e) What does 2.2 ppm, 2H, quartet indicate based on integration, splitting pattern, and chemical shift? Write in WORDS. (3) D) What does 4.8 ppm, 1H, singlet indicate based on integration, splitting pattern, and chemical shift? Write in WORDS. (3) g) DRAW the Carbon-Hydrogen pieces you have "discovered thus far. What atoms are missing? (3) b) What does the 13C peak at 190 ppm indicate? (3) i) What does the '8C peak at 56 ppm indicate based on the formula you deduced? (3) j) Put the pieces together making sure all the data matches and DRAW the mystery compound. o
