- NMR. Indicate how many signals appear in the proton spectrum of the(1) CICH=CH2(2) o-chloromethylbenzenearrow_forwardWhat does the (2H,ddd, J=8.3 Hz) mean? What would be the possible structure of this? The compound is C8H8O2arrow_forwardShown below is the C13 NMR spectrum of one of the three isomeric dichlorobenzenes. Is the compound= 1,2-dichlorobenzene 1,3-dichlorobenzene 1,4-dichlorobenzenearrow_forward
- Identify the structures of isomers H and I (molecular formula C8H11N).a.Compound H: IR absorptions at 3365, 3284, 3026, 2932, 1603, and 1497 cm−1b.Compound I: IR absorptions at 3367, 3286, 3027, 2962, 1604, and 1492 cm−1arrow_forwardHow many stereocentres are present in butan‑2‑ol and 2‑bromobutane?arrow_forwardCamphor, a saturated monoketone from the Asian camphor tree, is used among other things as a moth repellent and as a constituent of embalming fluid. If camphor has M+=152.1201 by high-resolution mass spectrometry, what is its molecular formula? How many rings does camphor have?arrow_forward
- 16-17 Propylamine (bp 48°C), ethylmethylamine (bp 37°C), and trimethylamine (bp 3°C) are constitutional isomers with the molecular formula C3HgN. Account for the fact that trimethylamine has the lowest boiling point of the three and propylamine has the highest.arrow_forwardHow could you use 1H and 13C NMR to help distinguish the following isomeric compounds of the formula C4H8?arrow_forwardCarvone is an unsaturated ketone responsible for the odor of spearmint. If carvone has M+=150 in its mass spectrum and contains three double bonds and one ring, what is its molecular formula?arrow_forward
- Predict the splitting pattern for each kind of hydrogen in isopropyl propanoate, CH3CH2CO2CH(CH3)2.arrow_forwardAn infrared spectrum of a mixture of methyl amine, CH3−NH2, and methylene imine, CH2=NH2, displayed absorptions at 1050 and 1640 cm−1cm−1, among others. Which of these two absorptions would you expect belongs to the C−N and which to the C=N stretch?arrow_forwardIdentify the peaks and structure of C10BrH7.arrow_forward
