Can you explain spectroscopy? Let's start with NMR Spectroscopy. What is the difference between a proton being enantiotopic and homotopic? What does it mean for a proton to be shielded or deshielded? How do you determine J (the coupling constant)? What does 'coupling is mutual' mean? How is that translated on the NMS Spectroscopy spectrum? Does that have to do with the polarity of the molecule? Is there an easier way to explain that? When thinking about C-13 NRM Spectroscopy, what it meant by the statement, "the carbons cannot integrate"? When looking at an NMR Spectroscopy spectrum, how do you know which peak belongs to which proton? (The intensity of the peak and the ppm of the peak) P.S. These questions come from after watching a lecture. There is no graded assignment attached to these questions. I simply do not understand the material.

a) Shown below is the 1H NMR (CDCl3 is the solvent) of butanal. The splitting pattern of each of the four peaks is provided. For each of the four peaks determine the number of hydrogens that belongs to each peak from the red integral line. Provide the number of the hydrogens in the order A, B, C, D. b) What happens when the radiofrequncy pulse in the NMR instrument matches the Larmor Frequncy of an NMR active nucleus? A. The electrons transition to the LUMO B. The nuclei undergoes a spin flip C. Nothing D. The bonds in the molecule stretch and vibrate

Explain any special features : IR: conjugation, resonance, H-bonding, etc. 1HNMR: enantiotopic, diastereotopic, H-bonding, Cis-trans, coupling constants, etc.
Can u explain in detail what the percentages mean what the spectral data means and what the structure is and how to find it thank u
predict the structure of the unknown compound using the image attached. Annotate all spectraEach spectra must be used to arrive at the answerThis means each piece of provided information should be annotated in some way depending on the type of analysis and information gained from it.calculate the HDI for proposed structure and provide the chemical formula
