9L.4 Learning Goal:To identify chiral molecules, understand opticalisomerism, and draw enantiomers.Optical isomers, or enantiomers, arenonsuperimposable mirror images of each other. Forexample, 2-chlorobutane and its mirror image (Figure 1) are optical isomers. Gloves are an example ofcommon objects with this property. Right and leftgloves are mirror images, but a right-handed glovedoes not fit on your left hand, and vice versa. Incontrast, the letter "A" is an example of an object thatis identical to its mirror image.FigureProperties of optical isomersOptical isomers generally have the same properties, differing only in their chemical behavior in a chiralenvironment (for example, with enzymes) and in the direction in which they rotate plane-polarized light.The / (levorotatory) isomer of an enantiomer pair rotates polarized light in a counterclockwise direction,whereas the d (dextrorotatory) isomer rotates polarized light the same amount, but in a clockwisedirection. A racemic mixture is a mixture with equal amounts of the I and d isomers.Part BYou have a racemic mixture of d-2-butanol and /-2-butanol. The d isomer rotates polarized light by+13.5°.
