Question

I’m supposed to label each peak with the correct letter but I’m struggling to understand it. I’m not sure if I’m doing these correctly. I don’t know how to do the 13C NMR.

Problem E: CH,02 -7 canoni IR shows a key stretching frequency at 1730 cm MS shows a base peak at 105 and a parention at 136 8 +1 -812=51 Benvenemy 'H NMR band A3H کانال OH OCH 3 (2H ZH 6 ppi 1C NMR 20 20 200 180 160 140 120 100 80 60 40 20 0

Answer 1

Ho Halo 37 Ha 3 H-NMR There will be u-eypes & H-NMR peaks Cho will show sunget at 8= 3.818pm (34) H6 & Hó' will show doublet at 8= 7.12 ppm (24) Ha & Ha' will show doublet at S=7.87 ppm (24) He will show suegel at & q. appen (314) -NMR C at S=129 ppm (12) Cq & CO 8= 132.3 ppm (21) C3&c5 8 = 114 ppm (21) cu at S= 166 ppm (IC) ez at 8 = 1910pm (IC) es at &= 55ppm (12) ?C=0 peak at 1730 cm Il mass on my = 136 parent peak m/2= los Base pear so you are doing correctly every step.
