Hi there..can u please answer the question i & ii
Step by step
Solved in 2 steps with 2 images
- Please help with these two. Explain your reasoning and show calculation of degree of unsaturation. Also, draw the structure of each compound on IR/NMR spectrum.answer with detail explanation , explain H1 nmr , IR , 13C ,DEPTNeed help, please. Using NMR only, how would you distinguish among 2-pentanone and 3-pentanone?
- How can you calculate the percentage of each menthene (1 and 2-menthene) isomers from an NMR spectrum? give formula and explanationAnnotate the IR spectra by labelling each of the major peaks as a functional group. Determine and draw the uknown structure based on the IR spectra.Next, draw the structure of C7H14O with hydrogen NMR and IR and the location of NMR.
- How could you use chemical shift and integration data in 1H NMR spectroscopy to distinguish between CH3OCH2CH2OCH3 and CH3OCH2OCH3? The 1H NMR spectrum of each compound contains only singlets.from the follwoing NMR spectra, which one is the compound? I, II, III or IV?1. Predict the maximum total number of possible peaks in the 13C NMR spectrum of sesamin (Hint: , keep in mind the molecule’s symmetry when predicting the # of NMR peaks) a. Indicate the number of non-aromatic peaks in the 13C NMR of sesamin b.Indicate the number of aromatic peaks in the 13C NMR of sesamin
- Explain why the β carbon of an α,β-unsaturated carbonyl compound absorbs farther downfield in the 13C NMR spectrum than the α carbon, even though the α carbon is closer to the electron-withdrawing carbonyl group. For example, the β carbon of mesityl oxide absorbs at 150.5 ppm, whereas the α carbon absorbs at 122.5 ppm.Propose a structure consistent with each set of data.Draw the structure of the ether that has a chemical formula C8H10O2, has a molecular ion peak at 138, and is represented by the IR, 'H NMR, and 13 C NMR below
