Carbon NMR Spectrum A has peaks at delta 71, 40, 19, and 12. Spectrum B has peaks at delta 72, 38, 31, 29, 22, 12, and 10. Which spectrum corresponds to 1-heptanol, and which corresponds to 4-heptanol. Explain your answer using structures.
Reaction of aldehyde D with amino alcohol E in the presence of NaH forms F (molecular formula C11H15NO2). F absorbs at 1730 cm−1 in its IR spectrum. F also shows eight lines in its 13C NMR spectrum, and gives the following 1H NMR spectrum: 2.32 (singlet, 6 H), 3.05 (triplet, 2 H), 4.20 (triplet, 2 H), 6.97 (doublet, 2 H), 7.82 (doublet, 2 H), and 9.97 (singlet, 1 H) ppm. Propose a structure for F. We will learn about this reaction in Chapter 18.
