Question

This property of a molecule is assigned “absolutely” by reacting with Pirkle’s alcohol or “relatively” by comparing it to glyceraldehyde (“gliss-er-AL-duh-hide”). Molecules that differ in this property bind differently to columns coated (20[1])in cyclodextrins. Chemists assign prefixes to molecules (20[1]0[1])with this (20[1])property by mentally shifting their lowest-priority atoms (20[1])into the (20[1])page. (20[1])Circular dichroism and (20[1])polarimeters (20[1]0[1])are used to assign the labels (*) R and S (10[3])to (10[1])the (10[2])optically (10[1])active molecules that have (10[1])this property. (10[1]0[1])Molecules with this property require a carbon to be bonded to four unique substituents. (10[3])Components (10[1])of racemic mixtures differ in this property. (10[1])For 10 points, name (10[1])this form of (10[1])mirror-image (10[1])isomerism (10[1]0[2])often (10[1])analogized to molecular (10[1])“handedness.” (10[3]0[1])■END■ (10[2]0[1])

ANSWER: chirality [or chiral centers; accept absolute configuration or optical configuration or chiral configuration or relative configuration; accept enantiomerism or answers like being an enantiomer; accept optically active or optical activity until it is read; prompt on isomerism until it is read; prompt on stereoisomerism]
