A better way to measure the percent composition of N-methylacetamide at 283 K would involve Select one: O a. Performing 64 NMR scans after 17 minutes of cooling and averaging the results O b. Irradiating the NMR tube with microwaves for 15 seconds in order to rapidly change the temperature to 383 K O c. More rapid cooling to 283 K, and collection of NMR spectra as single scans at several time points after the temperature had reached 283 K O d. Spraying the content of NMR tube at 333 K quickly into liquid nitrogen to give a solid matrix in which the conformational inter-conversions are frozen e. Bubbling chlorine gas through the NMR tube during cooling in order to minimize temperature gradients at the walls of the NMR tube

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.)
