You will check the outcome of reaction via infra-red spectroscopy what are the diagnostic functional group peaks for the following compounds? You should also indicate the stretching motions responsible for absorbance. Dilantin benzil (unreacted starting material) Urea (unreacted starting material)

Identify the following spectra. Please find peaks are assigned on the spectrum (~5-6 peaks). Label the peaks on the spectrum and place the structure of the compound in the box on the lower left-hand corner of the spectrum (from the table below, no numbering scheme). You do not have to indicate the exact wavenumber of the peak.

Which compound is correct for the given NMR spectrum? |(3) (2) (2) 2 1 PPM CN 1) 2) 3) Structure 1 O Structure 2 Structure 3

The following NMR corresponds to the molecule depicted below ran without reference. Assign the carbons to the peaks of the spectrum. Do this approximating the shift based on the atoms the Cs are attached to.  The question & answer options are attached.

Based upon the following NMR SPectrum please list the chemical shifts, multiplicity, and assignments of the major peaks

Identify the significant absorption peaks by labeling them right on the spectrumand includethe spectrum in your laboratory report. Absorption peaks corresponding to the followinggroups should be identified: C—H (SP3) C—H (SP2) C—H (aldehyde) O—H C=O C=C (aromatic)aromatic substitution pattern C—OC—X (if applicable)

Identify the structure of the compound a having the following IR. Label the spectra with the information you obtain (functional groups).  Compound a. Formula: C5H10O2

Draw the structure next to the matching spectrum and mark the peaks on the spectra that helped you pick that compound
