- Based on the 13C NMR data provided with multiplicity, deduce the structures of each of the benzenoid aromatic compounds below, where the molecular formula for compound is C10H14. a. 134(s), 131(d), 19(q)arrow_forwardHydrohalic acids (i.e., HCl, HBr, HI) add to the double bond of alkenes to yield alkyl halides. Shown below is the carbon NMR spectrum of an alkene of formula C5H10. What is the structure of this alkene?arrow_forwardThe 1H NMR spectrum of methylbenzene (C6H5CH3) recorded on a 500 Mhz spectrometer consists of signals at chemical shifts of 2.21 parts per million and 7.10 ppm. calculate the frequency, downfield of TMS, of each absorption.arrow_forward
- Assign 1H NMR chemical shifts (ppm values) to the hydrogens indicated in the structure below (see Expt. #4 for the spectrum). Place your answers in the spaces provided next to the structure.arrow_forwardDraw here the structure of 2-Chloropropene and encircle or point using arrows the different kinds of protons that would show in its 1H NMR spectrum.arrow_forwardWhat are the major IR absorptions in the functional group region for oleic acid, a common unsaturated fatty acid (Section 10.6A)?arrow_forward
- The 13C-NMR spectrum of 3-methyl-2-butanol shows signals at 17.88 (CH3), 18.16 (CH3), 20.01 (CH3), 35.04 (carbon-3), and 72.75 (carbon-2). Account for the fact that each methyl group in this molecule gives a different signal.arrow_forwardHexamethylbenzene undergoes free-radical chlorination to give one monochlorinated product (C12H17Cl) and four dichlorinated products (C12H16Cl2). These products are easily separated by GC-MS, but the dichlorinated products are difficultto distinguish by their mass spectra. Draw the monochlorinated product and the four dichlorinated products, and explainhow 13C NMR would easily distinguish among these compoundsarrow_forwardThe 13C NMR spectrum of 1-bromo-3-chloropropane contains peaks at δ 30, δ 35, and δ 43. Assign these signals to the appropriate carbons.arrow_forward
