How many signals will be expected in the 1H NMR spectrum of the following compound? Give detailed Solution..show work..dor

Predict the splitting pattern(s) you would expect for the proton(s) in the molecule below that will show in its NMR spectrum. Explain all answers.

Give structures for the following compounds based on the spectra given. Explain your logic.

what is their relationship, and will this matter when you look at the NMR?

What NMR resonance do you predict for Maltol: splitting, shift, and area? Explain your answer. (Tables may be used)

THIS CAN NOT BE HAND - DRAWN  Using a computer, illustrate the molecule from the molecular formula and interpret each of the following 1H NMR spectra. The integration for each peak is given above the peak. All spectra were taken from http://riodb01.ibase.aist.go.jp/sdbs/cgi-bin/direct_frame_top.cgi.

How many peaks in NMR will be given by the Hydrogen b of the upper image and how many by the Hydrogen b of the lower image and how do I find it?

III) Can 1H NMR spectroscopy be used to differentiate between the two compounds? Briefly explain why or why not. Predict the 1H NMR spectrum for each compound (include integration, multiplicity, and approximate chemical shift). For each set, be sure that you put them in a data table format!

find the structure of this nmr and explain why you think it matches the spectrum based on integartion, multiplicity and so on?

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
