A) an optically inactive compound a (c6h10o4) can be resolved into enantiomers and has the following nmr spectra: 13c nmr: ? 13.5, ? 41.2, ? 177.9 1h nmr: ? 1.13 (6h, d, j = 7 hz); ? 2.65 (2h, quintet, j = 7 hz); ? 9.9 (2h, broad s, disappears after d2o shake) draw either enantiomer, including wedge/dash bonds.(b) give the structure for an isomer of compound a that has a melting point that is appreciably different from that of a yet nmr spectra that are almost identical to those of a. include wedge/dash bonds.
