- The 1H NMR spectrum of bullvalene at 100 C consists only of a single peak at 4.22 . Explain.arrow_forwardAnswer the following questions about each of the hydroxy ketones: 1hydroxybutan-2-one (A) and 4-hydroxybutan-2-one (B).a.What is the molecular ion in the mass spectrum? b. What IR absorptions are present in the functional group region? c. How many lines are observed in the 13C NMR spectrum? d.How many signals are observed in the 1H NMR spectrum? e.Give the splitting observed for each type of proton as well as its approximate chemical shift.arrow_forwardExplain why the carbonyl carbon of an aldehyde or ketone absorbs farther downfield than the carbonyl carbon of an ester in a 13C NMR spectrum.arrow_forward
- 1. Predict the max. total number of possible peaks in the 1H NMR spectrum of episesamin a. Indicate the number of non-aromatic peaks in the 1H NMR of episesamin b. Indicate the number of aromatic peaks in the 1H NMR of episesaminarrow_forward( assign 13C nmr value of each carbon do 1st fivearrow_forwardAnswer the following questions about each of the hydroxy ketones: 1-hydroxybutan-2-one (A) and 4-hydroxybutan-2-one (B). a.) What is the molecular ion in the mass spectrum?b.) What IR absorptions are present in the functional group region?c.) How many lines are observed in the 13C NMR spectrum?d.)

- draw the strucutre based off the IR spectrum, 1H NMR spectrum, and 13C NMR spectrum for this compound. This compound is an ester that is commonly used as food additive to give foods and beverages a fruity flavor. Its molecular formula is C7H14O2arrow_forwardassign peaks from given H NMR spectra to the given compoundarrow_forwarddraw the ethanol strcture and then circle the protons on the structures and correlate the 1H's to the resonances (peaks) on the 1H NMR spectra.arrow_forward
- Show its chemical structure through NMR IRarrow_forwardUse the observed 1H NMR data to decide whether C and its dianion are aromatic, antiaromatic, or not aromatic. C shows NMR signals at –4.25 (6 H) and 8.14–8.67 (10 H) ppm. The dianion of C shows NMR signals at –3 (10 H) and 21 (6 H) ppm. Why are the signals shifted upfield (or downfield) to such a large extent?arrow_forwardThis NMR shows eugenol compund. which area in the NMR shows this copmound?arrow_forward
