The molecular formulas IR and 1H NMR spectra of different
organic compounds are shown below. the 1 H NMR all run that 300 MHz
in CDCl3. identify the compound by interpreting both the spectrum.
All piece must be assigned for the appropriate functional groups
(IR) and protons (NMR) to earn full credit.

4. The following spectra were recorded from different isomers with our molecular formula CH,CIO. They all contain a carbonyl functionality. Determine the structure of the different isomers. 9 8 7 6 5 4 2 * 10 OL........ 4 3 10
Interpreting NMR spectra is a skill that often requires some amount of practice, which in turn, necessitates access to a collection of NMR spectra. Virtual Chemlab Organic has a spectra library containing more than 700 'H NMR spectra. In this assignment, you will take advantage of this by first predicting the NMR spectra for two closely related compounds and then checking your predictions by looking up the actual spectra in the spectra library. After completing this assignment, you may wish...
