You have completed a synthesis and are now obtaining a melting point of the synthesized compound. The literature melting point is 126.2 °C - 128.4 °C. You determine the melting point to be 121.5 °C - 126.8 °C with a run at 2 °C per minute. You also determine that there is an erroneous signal in your IR spectrum. Which statement most accurately describes what you have going on here? O Your compound is not pure and is undergoing melting point depression. You may have added too much sample. None of these are correct. You may have added not enough sample. O There isn't an issue here, melting points are off all of the time.

I need help interpreting this IR spectrum of cyclohexanone. I'm not looking for anything in general just a description and explanation of what can be observed
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.)

Below is the spectrum for 2-hexanol which has a molecular ion peak of 102. Note that 2-hexanol's molecular ion is very unstable and rapidly undergoes degradation. This is why its molecular ion peak at 102 is almost nonexistent. Give the formula and try to describe the structure that corresponds to the base peak within the spectrum.
