2. 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. ¹H NMR Structure: ¹H NMR Structure: Peak 1 2 3 4 5 6 Peak 1 2 3 4 5 Chemical Shift (8) Chemical Shift (8) Multiplicity H* Multiplicity Peak 7 8 9 10 11 12 H* Peak 7 8 9 10 11 Chemical Shift (8) Chemical Shift (8) 6 12 † Specify the multiplicity as a singlet (s). doublet (d), triplet (t), quartet (a), or multiplet (m). Multiplicity H* Multiplicity H

A.) How many signals does the HNMR of the unknown C6H14O have? B.)Whats the ratio between the number of different hydrogens in the unknown compound C6H14O? C.)Explain splitting patterns of all the signals (in depth if possible the lecture confused me). D.)Explain the chemical shifts of the signals based upon the locations of hydrogens relative to the desheilding groups if any are present in the compound.   For A. I think there are 4 signals. For B. I think the ratio is 1:1:3:9 for the hydrogens on the HNMR spectrum. For the last 2 questions (C. and D.) the lecture confused me so an in depth of how you found the answer would be greatly appreciated. Also the unknown for the attached HNMR is C6H14O.

Predict the chemical shift of the following compounds?   find out different types of protons and give their  approximate chemical shift values based on their shielding and de shielding.

A.) How many signals are seen for the CNMR spectrum of the unknowns C6H14O? B.) Explain the chemical shifts of the signals seen based upon the location of the carbons that are relative to deshielding group if any are seen in the compound (unknown is C6H14O)?  For question A. I believe it is 4 signals. For question B. I know that none of the signals are in the deshielding are of the chart but are all located in the shielded region but i am unsure of how to determine the chemical shifts of the given signal. If possible an in-depth explanation would be greatly appreciated in order to understand this better.

3. For the structure shown, assign the signals to the respective hydrogen and carbon on the HNMR and CNMR spectra given below. O n R

1) Listen What are multiplicities of the signals for the groups identified, A, B and C in the H NMR Spectrum of the molecule shown below? В CH2 CH3 H3C CH3 C CH3 A Singlet, doublet, triplet Doublet, singlet, quartet Singlet, multiplet, triple Singlet, singlet, singlet

Arrange the following compounds in their correct order of chemical shift (). 1=Highest and 4=lowest. (All show just one signal in their 1HMR spectrum).

Predict how many peaks you would expect to observe in the ‘H NMR,spectrum of the compound shown below and indicate the integration value you would expect to see for each peak. Please explain how you got the answer. (It may be useful to label each hydrogen atom using lowercase letters).

Help please

Which one of the labeled hydrogen atoms in the given molecule will have the greatest chemical shift (furthest downfield)? م شد Ha Ho He Hd
