Below are the 1H NMR spectra of two compounds (the imine and the
amide) that you have synthesized in
this experiment (reductive animation using vanillin and
para-toluidine). For each NMR, assign each peak to the
corresponding hydrogen(s). Identify which
spectrum corresponds to which compound.
NMR Spectrum A:

Below are the NMR spectra of two compounds (the imine and the amide) that you have synthesized in this experiment. In each NMR, identify which peaks correspond to which hydrogens and label which spectra corresponds to which compound .(procedure provided below)
The molecular formulas IR and 1H NMR spectra of different organic compounds are shown below. the 1 H NMR all run that 300 MHz in CDCl3. identify the compound by interpreting both the spectrum. All piece must be assigned for the appropriate functional groups (IR) and protons (NMR) to earn full credit. The molecular formulas IR and 1H NMR spectra of different organic compounds are shown below. the 1 H NMR all run that 300 MHz in CDCl3. identify the...
Which compound gives the following spectra? For the 1H-NMR assign all signals. interpret mol peak and base peak in the mass spectrum if a mole peak exists. Assign at least two 13C signals. How does the IR spectrum support your finding? Check 200 180 160 120 80 60 40 20 0 140 a 100 ppm s, 3H t, 3 H d. 2 a. 2 H d. 2H s, 1 H 1 10 9 8 7 6 4 3 2 1...
4. Which two of the following compounds are consistent with the two IR spectra shown (one cach spectrum)? Draw the structure of the assigned compound by the respective spectrum. Assign label cach peak on each spectrum (outside fingerprint region) that corresponds to a bond in the structure
The two H1 NMR spectra below represent two of the four compounds shown below with the molecular formula C3H6O2. Which spectra corresponds with which structure?
Below are given 3 NMR spectra; each has a molecular formula (Compounds A, M and T). For each calculate its Index of Hydrogen Deficiency. Give a structure that is consistent with the spectrum and the formula. For full credit you must assign the signals in the spectrum to the protons in Your structure (Refer to Table 13.3 in text)
Thank you in advance! 1.

Lab 8: Instrumental Analysis You are given seven unknowns, all of which are white or brown powders. Use the provided IR and 1H NMR spectra to assign Unknowns 1-7 to the given compounds. Label all spectra and briefly explain how you made your determinations.unknown 1: unknown 2: unknown 3: unknown 4: unknown 5: unknown 6: unknown 7:
4. Consider the following two diastercomers: Both compounds generate 'H NMR spectra with the following signals: A multiplet between 7.20-7.63 ppm with an integration of 5H Two separate doublets between 5.70-6.50 ppm, each with an integration of 1H A singlet around 1.30 ppm with an integration of 9H Despite the similarities, how could you differentiate between the H NMR spectra of these isomers? 5. Assign each set of protons to their appropriate signals in the 'H NMR spectrum shown below....
NEED HELP WITH B) C) D) E) F) and G) that apply to the spectra below. OTHER ANSWERS ARE THERE TO SUPPLEMENT Thank you! 5. Using the GC mentioned in question 4 and the values listed on the chromatogram for the height and width (at half height) of each peak, calculate the percent composition for each product (A, B and C). Be sure to show your work. Area of peak A = 125 x 8 = 1000mm2 Area of peak...
