Why do aldehydes, esters, and amides all have a strong absorption in the 1630-1780 cm1 region of their IR spectra? A) The bond between H and the sp³-hybridized C in these functional groups vibrates in this energy range. B) Each of these functional groups has at least two resonance structures, and the different vibrations of the resonance structures give off energy in this region. C) The bond between O and the sp²-hybridized C in these functional groups vibrates at a frequency in this energy range. D) Light at this wavenumber causes the average C to O bond length to increase which causes more of this light to be transmitted. E) An electron in the bond of these functional groups gets excited to the * orbital.
By looking at the H1 NMR spectra, draw the structure for the solid organic unknown compound and explain the process you used to determine the identity of your compound. Show all H atoms and label each equivalent set of atoms as A, B, C etc in the structure. Then, calculate the expected chemical shift for each of the equivalent set of H atoms in the structure. Clearly label your calculations Note: (Clearly list the tables used, base shift values and what correction factors were used.)
