Molecules with three bidentate chelate rings that have this property can undergo processes named for Bailar, as well as Ray and Dutt. Cram’s rule describes how molecules with different forms of this property are preferentially formed. Meso compounds (15[1])notably (15[1])lack this (15[6])property. The (15[2])use (15[1])of (15[2])Mosher’s acid to separate (15[1])molecules based on this property has been (15[1])superseded by using Pirkle-type or cyclodextrin-containing (*) stationary phases in a namesake form of chromatography. An ee of 0% means that two (10[1])equal components of a mixture have opposite values (10[1])of this property, making it (10[1])racemic. This property (10[1])distinguishes (10[1])enantiomers from each (10[2])other. For 10 points, compounds with what (10[1])property cannot be superimposed on their mirror images? ■END■
