Using proton NMR spectra, how could a chemist distinguish between the following two compounds? H. H. СОСН Ph COCH; Ph H. Compound A Compound B The alkene protons in compound A display a larger coupling constant. Compound A and compound B show a different number of signals in the proton spectrum. The alpha alkene proton would be more shifted than the beta alkene proton in compound B Proton NMR spectroscopy cannot be used to distinguish between these compounds. The alkene protons in compound B display a larger coupling constant.
