- How many 1H NMR signals does each alkene exhibit?arrow_forwardAssign the protons to the appropriate 1H NMR signalarrow_forwardThe 'H NMR spectrum of compound A (C3H100) has four signals: a multiplet at 8 = 7.25-7.32 ppm (5 H), a singlet at d = 5.17 ppm (1 H), a quartet at d = 4.98 ppm (1 H), and a doublet at ô = 1.49 ppm (3 H). There are 6 signals in its 13C NMR spectrum. The IR spectrum has a broad absorption in the -3200 cm-1 region. Compound A reacts with KMNO4 in a basic solution followed by acidification to give compound B with the molecular formula C7H6O2. Draw structures for compounds A and B.arrow_forward
- Based on the structures given below, which of the following statements is entirely true? Quinoline NH Isoquinoline Indole Isoindole All four compounds are non-aromatic, with 12 pi-electrons each and are equal in basicity. Only quinoline and Isoquinoline having 10 pi-electrons each are aromatic while indole and isoindole are antiaromatic having 8 pi-electrons each The nitrogen atoms of quinoline and isoquinoline are sp2 hybridized while the nitrogen atoms of indole and isoindole are sp³ hybridized. All four compounds are aromatic, with 10 pi-electrons each and are equal in basicity. All four compounds are aromatic, with 10 pi-electrons each, and with quinoline and isoquinoline being stronger bases than indole and isoindarrow_forwardWrite out the structure of the products and predict an NMR spectrum from each one.arrow_forwardWhich of the diethylbenzene isomers (ortho, meta, or para) corresponds to each set of 13C NMR spectral data?[A] 13C NMR signals: 16, 29, 125, 127.5, 128.4, and 144 ppm[B] 13C NMR signals: 15, 26, 126, 128, and 142 ppm[C] 13C NMR signals: 16, 29, 128, and 141 ppmarrow_forward
- Explain why the carbonyl carbon of an aldehyde or ketone absorbs farther downeld than the carbonyl carbon of an ester in a 13C NMR spectrum.arrow_forwardExplain why aromatic protons resonate downfield and aliphatic resonate upfield.arrow_forwardAssign the resonances in this C-NMR spectrum.arrow_forward
- Look at NMR and answer #2,3 and 4arrow_forwardWhich set of underlined hydrogens has its 1H NMR signal at a higher frequency?arrow_forwardWhen compound A (C5H12O) is treated with HBr, it forms compound B (C5H11Br). The 1H NMR spectrum of compound A has a 1H singlet, a 3Hdoublet, a 6H doublet, and two 1H multiplets. The 1H NMR spectrum of compound B has a 6H singlet, a 3H triplet, and a 2H quartet.
