Expt 2 Free Radical Halogenation Reading Assignment - Lab Manual # 16, pp 127-132. Mohrig Technique 17.4c (pp 214-215). Experimental Procedures We will use the procedures as described in the lab manual, except for in part B we will use proton NMR instead of GC to determine the product ratio. Thus, the crude product after alumina filtration is transferred to an NMR tube, CDCl3 added, and the proton NMR obtained. Spectrum Analysis After integrating the spectrum, you need to identify as many peaks as possible and pick out one that can be integrated to represent the relative amount of the 1-chloro product and another one to represent the 2-chloro product. Use the integration values of these peaks to determine the product ratio. (Remember that each integration value needs to be corrected for the number of hydrogens it represents.) Assigned Questions for Lab Report. Assigned questions are #3 and #6 in the lab manual and the following:
