For each of the following structure, describe the peaks you would expect to see if you run the compound through IR spectroscopy
I have solved the problems.
For each of the following structure, describe the peaks you would expect to see if you...
Order the hydrogens for each molecule in the order you would expect to observe the peaks (upfield/downfield) for 3-methylbutylacetate, 3-methylbutanal, 3-methyl-1-butanol. Report the peaks as you see them for the proton NMR using the tables below: Compound: Peak shift mulitplicity Assignment Compound: Peak shift mulitplicity Assignment Compound: Peak shift mulitplicity Assignment Look at the 13C-NMR and list the peaks and assign them to the carbons in each. What similarities did you notice with the NMR peaks in the three compounds?...
how many peaks in an IR spectrum would you expect to see that would characterize an alcohol functional group
Need help with spectroscopy Please label all peaks, in the IR (except fingerprint region) and NMR spectra Draw the structure/ compound that would produce these spectra 1. A compound with molecular formulacsH7NO) displays the following IR, and 13C NMR spectra. Propose a structure for this compound.
