In this experiment products 2, 3 and 4 are produced in slightly different amounts in the three fractions you collect. You are able to quantify the amount of 2 and 3 by examining the 'H-NMRS for each fraction. Before you can do this you should be able to recognise what you expect to observe in the olefinic region of the NMR.

A two-step synthesis of virstatin reactions are given. Give the yield and % yield of each synthesis. Make a labeled drawing of the equivalent hydrogens for each product. Using the NMR drawings given for each structure, describe how the hydrogens are seen on the NMR by chemical shift, integration, and splitting. Make sure your NMR matches the structure of the product you are proposing. For example: “the triplet at 4ppm, integrating to 2, represents the methylene group (Ha) attached to the nitrogen, as it deshielded by the electronegative element and is split by the neighboring methylene group. If you did not make the intended product in step one of the two step synthesis, explain why it did not matter in regards to further reacting the products to form virstatin. Data Mass of 1,8-naphthalimide used: 0.2528g Mass of potassium carbonate used: 0.2624g Recovered virstatin ethyl ester: 0.2602gMass of virstatin ethyl ester used in step 2: 0.1066g Mass of recovered virstatin: 0.0035g…
In the expanded region of 1H NMR for 4-t-butylcyclohexanols, the peak at 4.05 ppm integrates to 1.0 while the peak at 3.52 ppm integrates to 2.52. Please use this information to calculate the percentage of each isomer in the sample. QUESTION- Based on the 1H NMR, Please explain the cis vs. trans product ratio. Is it consistent with the expected results? Why or why not?
c) FT-IR spectra of both nitro and nitrito-isomers were recorded immediately after preparation. Then small samples were exposed to heat (in oven) and their spectra were recorded again.
Look at the structure of the starting material (9-anthraldehyde) and the product of the Wittigreaction. Describe the main differences you would expect between the 1H NMR of thisstarting material and the product. (Include comments about integration and shift values.)
Following is a 1H-NMR spectrum of2-butanol, Explain why the CH2 protons appear as a complex multiplet rather than as a simple quintet.
Propose a structure for your product and justify your assignment based on its melting point and its 1H NMR spectrum. The analysis of the 1H NMR spectrum should include a detailed assignment of each of the NMR resonances to the protons found in your structure. NMR analysis should include reasoning used to exclude other aldehydes and ketones from your structural assignment. For example, no signals were observed between 0-4 ppm indicating no H atoms bound to sp3 hybridized carbons. It can be concluded from this observation that no ketone or aldehyde that would retain a H bound to sp3 hybridized carbons were used as starting materials.
An organic lab student carried out the reaction of methylmagnesium iodide with acetone(CH3COCH3), followed by hydrolysis. During the distillation to isolate the product, she forgot to mark the vials she usedto collect the fractions. She turned in a product of formula C4H10O that boiled at 35 °C. The IR spectrum showed onlya weak O¬H stretch around 3300 cm-1, and the mass spectrum showed a base peak at m>z 59. The NMR spectrumshowed a quartet (J = 7 Hz) of area 2 at d 3.5 and a triplet (J = 7 Hz) of area 3 at d 1.3. Propose a structure for thisproduct, explain how it corresponds to the observed spectra, and suggest how the student isolated this compound.
2 The IR and 1H-NMR spectra of a compound with molecular formula C4H7ClO2 are shown below. Your objective as a group is to propose a structure for this compound, explaining how you reach your decision. Using all the information you have been given, in a post with others in your group share your initial ideas about the possible structure of the compound. Then use comments to interact with the other students in the group and propose a final answer to the problem. In the comment phase, you should comment on the postings of at least two other students.
Consider the monosubstituted benzene reagent X. Nitration of X yields product Y. Product Y is analysed by 1H and 13C NMR spectroscopy (see Figures 1 to 4). Determine the structure of X and Y on the basis of the spectral data provided.
