- Choose the best explanation for why -OH and -NH peaks are often broad singlets in a ¹H NMR spectrum. A) The greater electronegativity difference in the N-H or O-H bond compared to a C-H bond makes the peak broader. B) The greater mass involved in the N-H or O-H bond compared to a C-H bond makes the peak broader. C) The hydrogen nuclei on the carbon next to the -OH or -NH are too far away to impact the multiplicity. D) Protons in OH or NH groups are acidic enough to rapidly exchange between different molecules, so the coupling to vicinal hydrogens is not clearly observed.arrow_forward2.
