An optically inactive mixture A (C,H,O₂) can be resolved into enantiomers and has the given NMR spectra. • 13C NMR: 8 13.5, 841.2, 8 177.9 ¹H NMR: 8 1.13 (6H, d, J = 7 Hz); 8 2.65 (2H, quartet, J = 7 Hz); 89.9 (2H, broad s, disappears after D₂O shake) A. Draw either enantiomer. Use wedge and dash bonds, including for any H atoms on a chirality center. Select Draw Rings More. Erase B. Give the structure for an isomer of mixture A that has a melting point that is appreciably different from that of mixture A yet NMR spectra that are almost identical to those of mixture A. Use wedge and dash bonds, including for any H atoms on a chirality center. Select Draw Rings More
