1. Problem Day 1 Answers CH343 Bruce A. Hathaway

2. Problem 1: Carbon NMR Seven types of Carbons: 4 benzene carbons and 3 sp 3 carbons

3. Problem 1: MS Molecular weight = 154; possible Cl, due to peak at 156 that is one-third the size of the 154 peak.

4. Problem 1: Proton NMR

5. Problem 2: Carbon NMR Four types of carbon: all sp 3

6. Problem 2: MS Odd molecular weight: odd # of N’s No Cl or Br

7. Problem 2: Proton NMR

8. Problem 3: Carbon NMR Eight types of carbon: 1 C=O, 4 benzene C’s, and three sp 3 C’s.

9. Problem 3: MS Even molecular weight: 0 or even # of N’s No Cl or Br

10. Problem 3: Proton NMR
