Web7 The R,S diastereomer of tartaric acid is a meso compound. Meso compounds have a) an even number asymmetric atoms of opposite configuration. b) an internal mirror plane bisecting the molecule. Each half of the meso compound is the mirror image of the other half and “cancels” the optical activity of the other, thus the molecule is achiral. Why are the … WebWhen we try to superimpose A onto B, we find that we cannot do it. A and B are both chiral molecules, and they are enantiomers of each other. 2-propanol, unlike 2-butanol, is not a chiral molecule. Carbon #2 is bonded to two identical substituents (methyl groups), and so it is not a chiral center.
