Please DRAW a simulation of a 2D NMR (H-H COSY and HSQC) for Glyoxal and glycoaldehyde. Will give a thumbs up rating!!! Please see the example for how it should look: 8:28 pm

I have an NMR spectrum. There are 5 peaks.  There is a doublet at 9.6 ppm (integrates to 2H) where aldehydes usually arise, don't know why there is a doublet. There is another doublet at 6.8 ppm, again integrating to 2H.  There is a singlet at 4.5 ppm, integrating to 1H.  There is a quartet at 3.4 ppm integrating to 2H, and lastly there is triplet at 1.2 ppm integrating to 3H.  i recofnize the ethyl group but don't understand the peak at 9.6 unless it is not an aldehyde.

Draw the structure of the correct compound on each spectrum and match each type of hydrogen on the structure to the corresponding peak on the spectrum. Thanks

Is this HNMR spectrum for 3-methoxybenzoic acid, 4 methoxybenzoic acid or 4 methylbenzoic acid? Please explain why and explain peaks, shifts, etc.

Please help me identify the structure of this NMR! Thank you!! 11 10 8. 7 6 5 4 3 2 1 HSP-00-768 ppm

A 13C NMR spectrum is shown below. Match the spectrum with the proper structure.

THIS CAN NOT BE HAND-DRAWN! Interpret each of the following 1H NMR spectra. The integration for each peak is given above the peak. See the example for methyl ethyl ketone. All spectra were taken from http://riodb01.ibase.aist.go.jp/sdbs/cgi-bin/direct_frame_top.cgi.

2) On spectra 2 are the mass, IR and 13 C and 1 H NMRspectra of an organic compound.a) From these spectra, determine the structure of the molecule. Rememberto ignore the triad in the 13 C NMR spectrum at 7 ppm that comes from theNMR solvent. b) Draw the structure of the molecule and label each hydrogen with a letter(A, B, C...). Then fill in the peak assignment table below.  hydrogen chemical shift integration splitting pattern couples to

Draw high resolution NMR spectra of the following compounds. Go to SDBS database and verify the spectra. Also, find IR spectra of each compound. 1. Ethanol 2. Acetic acid 3. Benzene 4. Ethyl acetate 5. Acetone 6. Diethyl ether 7. Dimethyl ether 8. Propanol- 9. Propanal

The IR spectra for acetaminophen and phenacetin are shown below. a. Identify which spectrum is for acetaminophen and which is for phenacetin. b. Label the key bond/functional group signals on each spectrum.
