Question

1. (2s-3s) tartaric acid, HOOCCH(OH)CH(OH)COOH has an opticalactivity of -12 and mp of 170. a.) what is the absolute configuration, specific rotation andthe melting point of its enantiomer?    answer: 2R,3R, +12, 170 b.) is the enantiomer destrorotatory r levorotatory? write thechemical structure of this enantiomer    answer: levorotatory   CHOOH          H___l____OH         HO___l____H          l          COOH c.)write the chemical structure of a diasteriomer of theseenantiomers, place a star on the chiral centers and determine theabsolute configuration of each chiral center.       COOH      H____l*_____OH      H____l*_____OH       l       COOH    2R, 3R d.) Is this diasteriomer optically active or not? No, because due to a planar symmetry a.) what is the absolute configuration, specific rotation andthe melting point of its enantiomer?    answer: 2R,3R, +12, 170 b.) is the enantiomer destrorotatory r levorotatory? write thechemical structure of this enantiomer    answer: levorotatory   CHOOH          H___l____OH         HO___l____H          l          COOH c.)write the chemical structure of a diasteriomer of theseenantiomers, place a star on the chiral centers and determine theabsolute configuration of each chiral center.       COOH      H____l*_____OH      H____l*_____OH       l       COOH    2R, 3R d.)
