Experimental Data Only report the IR absorptions that provide diagnosis for the major functional groups. Copies of your spectra will be included in your lab report with this information written on the spectra. However, the information should also be included in the body of the report in a text format similar to the example given below IR cm1: 1735 (C-o); MS:...

1. How many signals do you expect to see in the 'H NMR of the following compounds? Label each H and use the same label (eg. Ha) for any equivalent H's. CH, CH CH CH O CH, CH,CHCHCHCH3 CH2CH2CH OCHCH; CH3 CH3 CH 2. For each compound label the proton or set of protons that gives the signal at the highest chemical shift (largest ppm) a next highest band so on. H CHỊCH,CH, SOCH, CH,CH, CH CH3CHCHCH
