1) How many peaks do you expect to see in the "C NMR of the following compound?[2 marks] Meo A) 3 B) 4 CIS 08 2) If we acquire a H NMR spectrum for the compound below, how will the resonance for the circled proton appear? [2 marks] ito D) A) B) 3) What functional groups are present in this molecule? [2 marks] A) alkyne B) alkene C) aromatic ring D) carboxylic acid Look at the IR spectrum below. What functional groups are present in this molecule? 5.00 3069 2986 2880 MALTA 1039 766 1689 1578 1479 11300 4000 3000 2000 1500 1000 500 cm
Look at the proton NMR spectrum below. The spectral data are tabulated as well so you can see the exact chemical shifts and coupling constants. The compound has a molecular formula of C,H,O, Determine the structure of the compound, and explain your reasoning. It is the same compound as the IR spectrum from the last slide. NMR 7.86 (1H,17.8 Hz) 7.43 (1H, dd, J = 7.8, 8.9 Hz) 6.98 (1H, dd, J = 8.4, 89 Hz) 6.94 (1H, d./ = 8.4 Hz) 4.50 (2H, 1./6.4 H) 2.77 (2H1.-6.4 H) 8 7 6 5 ppm 4 3 2 1 0 This is the El-MS spectrum for the same compound. Now that you know the structure, suggest a structure for the major fragment at m/z 120 100Eu.MS W2120 M mt 148 80- 60 m/292 Relative tensity 20 25 50 75 m/z 100 125 150 175
