Chirality Learning Goal: To identify chiral molecules, understand optical isomerism, and draw enantiomers. Optical isomers, or enantiomers, are nonsuperimposable mirror images of each other. For example, 2-chlorobutane and its mirror image (Figure 1) are optical isomers. Gloves are an example of common objects with this property. Right and left gloves are mirror images, but a right-handed glove does not fit on your left hand, and vice versa. In contrast, the letter "A" is an example of an object that is identical to its mirror image. Figure 1 Chiral molecules Molecules that exhibit optical isomerism are called chiral molecules. Molecules that are not chiral are called achiral. A carbon atom that has four different substituents in a tetrahedral arrangement will be chiral. For example, C2 of 2-chlorobutane has four different substituents: -H, -CH3, -Cl, and -CH2CH3. Identify which of the following molecules are chiral and which are achiral. Drag each item to the appropriate bin. You have a racemic mixture of d-2-butanol and l-2-butanol. The d isomer rotates polarized light by + 13.5 degree. What is the rotation of the polarization of light of your mixture? Express your answer in degrees. Two products, structural isomers of each other, are possible for the bromination of butane via the reaction CH3CH2CH2CH3 + Br2 rightarrow ? heat or light One of these products exhibits optical isomerism. Draw this product. Assume mono substitution. Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default. Epoxides: Draw the enantiomers of 2-methyloxirane Draw the enantiomers of 2-methyloxirane (shown below). Interactive MarvinView Draw the molecules on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default. Show the appropriate stereochemistry by choosing the dashed or wedged buttons and then clicking a bond on the canvas.
