Review the NMR analysis section of the procedure (pages 7W-15 and 7W-16) and results/spectra document. According to the 'H NMR of the reaction in acetone, what is the J coupling constant for theolefinic hydrogens? You may have to review how to calculate coupling constant in hertz from chemical shift differences in ppm. 0.02 Hz O 8 Hz 2 Hz O 14 Hz
