(a) an optically inactive mixture a (c6h10o4) can be resolved into enantiomers and has the following nmr spectra: 13c nmr: δ 13.5, δ 41.2, δ 177.9 1h nmr: δ 1.13 (6h, d, j = 7 hz); δ 2.65 (2h, quartet, j = 7 hz); δ 9.9 (2h, broad s, disappears after d2o shake) draw either enantiomer; use wedge/dash bonds, including for any h on a chirality center.
