Show all signals,including an accurate representation of splitting, intensity and position. Assume NO signal overlap (i.e. ifyou expect signals have similar chemical shifts, just place them next to each other). Clearly label theintegration value for each signal. Indicate the correlation between each proton (HA, HB, etc) and eachsignal (label signals A, B, etc.) by using the standard subscript system that we have been using for otherproblems.

Please help me with 1 and 2 thank you
1. NMR analysis: Draw the full structure of diphenylmethanol. Show all bonds to the hydrogens. Label the different sets of hydrogens (i.e. Hạ. Hp, H1, H2, etc) based on which ones are equivalent and which ones are not. Assign each set of hydrogens with a specific signal on the spectrum. Create a table that summarizes: the chemical shift, integration, multiplicity, proton assignment, and justification of each signal.
Please answer the questions and provide detailed explanations.
4. Determine the multiplicity (singlet, doublet, etc) of each signal in the expected 'H NMR spectrum of the following compound. Circle the carbon atom that would be the most deshielded in the 13C NMR spectrum. مله Ν H
Signature: Q1. For each of the following molecules, determine how many signals you would expect to see in an ¹H-NMR spectrum of the molecule. Additionally, label each of the hydrogen atoms (A, B, C, ...) such that those in the same chemical environment are given the same designation and determine the expected splitting for all protons (s, d, t, q, m etc.). a. b. Q2. How many 13C signals would you expect for the following compounds? a. LOH b. CI H
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
4.Predict the NMR spectra for each of these two compounds by listing, in the NMR tables below, the chemical shift, the splitting, and the number of hydrogens associated with each predicted peak. Sort the peaks from largest chemical shift to lowest. 5. Using the peak information listed in the tables for both structures, assign each peak to that portion of the structure that produces the peak in the NMR spectrum.
6.
For each of the ten spectra you should determine which peaks are the most important for identification purposes, what their wavenumber values are, and what specific bonds and/or functional groups they indicate. Record those in the spaces under each spectrum. You don’t have to use each space. Then, from the list of possible compounds, identify what compound is responsible for each spectrum. Realize that these are all of real samples and there may be impurities present that cause weak peaks which would not normally be caused by the compound, such as the one at 3450 cm-1 in Spectrum 1.
