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

Please assign proton NMR and IR signals to the peaks indicated in the spectra with arrows (for triphenylmethanol) so ignore the first part. Please explain how/ why

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.

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

please draw the molecule and label it based on the data in the sheet and use the label in the data table.

Does the IR spectroscopy align with the product below and if so why?
