2. Circle the molecule below that matches the 'H NMR spectrum. 2.0 1.0 6.0 3.0 3.0 2.5 2.0 1.5 1.0 0.5 0.0 d (ppm)

analyze this H-NMR spectra of Vanillyl Alcohol. Results were gathered after a lab of synthesis of vanillyl Alcohol..

a) Make a table of the chemical shift, multiplicity and number of hydrogens for each 1H-NMR signal. b) Propose a structure consistent with the data and assign each proton in your structure to a signal in the NMR spectrum.

Please give me the right answer

In identifying the NMR regions, would the small round peak be classified as a singlet or doublet?  Also, what is the key in identifying NMR regions (Multiplet, doublet etc.)

Looking at the NMR, how can you determine the compound is cyclohexane carboxaldehyde?  Distinguish all the ppm (be detailed)

CAHOBR compound Which C,H,Br compound would give the following proton NMR spectrum? Enlargements of the signals are shown above each one. The integration is shown in a little box in the upper left. Chem shift 1.05 Rel area 0.00 1.97 1.00 3.31 2.00 TMS 3. 2. 0 ppm 4 6. Chemical shift (6) 10 c) 2-bromo-2-methylpropane d) 2-bromobutane 1-bromobutane b) 1-bromo-2-methylpropane

None

Draw the structure for the H-NMR.

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.
