Attrition from glass beads promotes the formation of crystals with this property via its namesake “amnesia.” Small imbalances in this property are amplified in an autocatalytic reaction of pyrimidyl aldehydes, the Soai alkylation. Deuterating the side chain of glycine causes it to gain this property. Cyclodextrins are used in chromatography columns used to separate molecules with this property. Explaining the uniformity of this property among (*) sugars and amino acids, or “homo”-[this property], is a key problem in the origin of life. “Auxiliaries” with this property are used to direct asymmetric syntheses. Molecules with this property are labeled “R” or “S” (10[1])based on the configuration of their stereocenters. For 10 points, give this property of molecules that cannot be superimposed onto their mirror image. (10[1])■END■ (10[1])
