Give an analysis of Benzene NMR Spectrum Questions: Proton environment How many types of proton environments are present? How many different NMR signals would you expect?  Chemical Shift Give the chemical shift:  Splitting pattern Number of neighboring protons? Number of lines expected? Draw the chemical structure.

Spectrum 2. Match the correct compound to the given NMR spectra. On the spectrum, match the signals on the NMR with the protons of the structure (use arrows to point or use letter or number designations).

label each peak (A, B, C...) and assign each peak on a drawing of the compound (compound shown below) Draw the structure and match each proton peak to a proton in your compound by labeling both the NMR peak and the H atom(s) in the structure with the same letter or by labeling the H atom(s) in the structure with the ppm of the appropriate peak.

How can I find the numbers of hydrogens per each peak on the NMR chart of the image?

Identify all the peaks in the H-NMR and C-NMR spectrum. Record the chemical shift, the splitting, and the number of hydrogens for each peak in the NMR table. Please fill in the data similar to the example table down below.

Q1. How many unique protons are in the following molecules (how many signatures/peaks would you expect to see in a 1H NMR spectrum)?    Q2. The following NMR spectrum is of 1-chlorobutane. Draw the structure, and match the peaks to their respective protons on the structure:  Q3. The following NMR spectrum is of ethyl 4-hydroxybenzoate. Draw the structure, and match the peaks to their respective protons on the structure:   Q4. Determine the identity of the following unknown, then draw the structure, and match the peaks to their respective protons on the structure (hint – the molecular formula is C8H18O):                                           -4-                                                                                 -2-                        -12-

a. How many signals are in its 13C NMR spectrum?b. Which signal is at the lowest frequency?   CH3CH2CH2Br

For each compound, give the number of 1H NMR signals and then determine how many peaks are present for each NMR signal.

Using the molecule below, how many signals are present in its 13C NMR & 1H NMR?

Part E How many signals are in its 13C NMR spectrum? H3C H_CH3 Br Express your answer as an integer.

How many H-NMR signal can be detected in this molecule？Draw the H-NMR graph please.

help me draw 13C NMR spectrum of the image below

Find how many peaks will appear in the proton (1H) NMR spectrum and carbon (13C) NMR spectrum of each molecue.  Don't take into account splitting in the proton(1H) NMR

Could someone help me label the unique populations of hydrogen that would show up in an NMR spectrum for these two compounds? Thanks and it would also help if there was an explanation.

Could you please mark all the peaks. and draw the compounds.  thank you

Please help

Make a numbered list of how you would go about interpreting an NMR.

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

1. How many different sets of equivalent aromatic (benzene ring) carbons can be seen in the 13C NMR spectrum of your unknown monosubstituted benzene starting material? A. Are there any peaks for non-aromatic carbons in the 13C NMR spectrum of your unknown monosubstituted benzene starting material (yes or no)? B. If yes for part A, please list the corresponding ppm value(s) for any non-aromatic carbon(s)?

Look at NMR and answer #2,3 and 4

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!

Show work with explanation needed. Don't give Ai generated solution

I need solution show

Please show complete answer. Answer the following questions for compounds L, M, and N drawn below. a.How many signals are expected in the 1H NMR spectrum? b.Into how many peaks is each signal in the 1H NMR spectrum split?

6) a)Assign the peaks in the 'H NMR shown below to the correct protons in molecule shown below. The portion of the NMR between 8-6.5 ppm has been magnified for easier viewing. (Hint: Draw resonance structures to distinguish the benzene and alkene Hs. 1H 2H 1H الس 2H CHH BH. CH3 A CH3 D H3C N H CH3 H 6H 6H PPM b) Draw a resonance that shows how you can differentiate the alkene hydrogens in the NMR. It is ok to have more than one positive and negative charge for the resonance structures with a NO2 group.) H H3C-N CH3 CH3 CH3
