- The difference between UV spectroscopy of Benzaldehyde and UV of Benzonitrilearrow_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_forwardThe NMR spectrum of 3-nitroaniline was taken in deuterated dimethylsulfoxide (DMSO), not CDCl3. Why? a) The residual CHCl3 peak would get in the way of the aromatic peaks in the product.b) 3-Nitroaniline is not soluble in CDCl3.c) DMSO allows visualization of the peaks for the NH2 group.d) 3-Nitrobenzamide is not soluble in CDCl3.arrow_forward
