Step 1: Brief Description The given compound is 4-aminobenzoic acid. The IR and NMR spectrum of this compound also given. Determine the spectrum. Step 2: Determination of IR data The peaks are identified as following: Two bands at 3300 & 3230 cm. This is due to asymmetrical and symmetrical N-H stretching of NH₂ group. A broad stretching between $200-2500 cm** - This broad stretching is due to O-H in carboxylic acid group. Band at 1680-1700 cm¹. C=O Stretching 1600 cm C-C-C (aromatic carbon) Step 3: Determination of PMR spectrum Splitting patterns: It should be noted that spin-spin splitting is observed only between nonequivalent neighboring protons. Equivalent protons do spin-spin couple with one another but splitting is not observed. Chemical shift: A highly shielded proton has a low chemical shift and a highly deshielded proton has a high value of chemical shift. The given peaks are of following: Proton Level Chemical shift (ppm) Relative integration Multiplicity ABC -11.9 7.8 8.3…

Jacobsen's catalyst was used for the expoxidation of styrene to form styrene oxide. Label the proton NMR spectrum assigning peaks to the protons.
How can I find the numbers of hydrogens per each peak on the NMR chart of the image?
I am looking at this unknown NMR sheet, and I am trying to identify an amine/aldehyde. I also have the IR sheet, but I should be able to figure that out once I have the identity of the unknown. I think it is an aniline with an ether, but I am not sure and don't know all the steps to take when looking at an NMR. Could you explain what I am looking at? Thank you!
We are trying to determine the substitution pattern on an aromatic ring by looking at the region from around 6 to 10 on the proton NMR spectrum. 10 We don't care what the side chain(s) is/are, we're just calling them F, and K (if needed). Which of the following compounds is represented by this proton NMR? F D OB OA A O C B C D
II. How many number of distinct proton environments would you predict if you observe three (3) signals in an NMR spectrum?
Please do both neat and clean correctly... Provide only typed answer solution. Handwritten solution not needed thank you
ANSWER WILL BE MARKED AS WRONG IF YOU HAND DRAW USE A COMPUTER PROGRAM TO ILLUSTRATE AND TYPE THE EXPLANATION
do both correcly asap or else i will report , do both must within 30 min
Complete the table with at least 3 Major NMR shifts. (propylbenzoate)
please answer do not image format
