How can IR spectroscopy be used to monitor the progress of each of the following reactions (if reaction went to completion and/or check the purity of the final product)? What absorptions would be observed in the IR spectrum? And if IR spectroscopy could not have been used, briefly explain why.arrow_forwardCan I get this question answered with an explanation Why is it better to acquire the 1H-NMR spectrum in DMSO-d6 and not in CDCl3?arrow_forwardChoose 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_forward
