3-Methylhexane, optical isomers

FIGURE 18.3 The molecule of 3-methylhexane on the right is the mirror image of the one on the left. Each group is represented by a sphere of a different color. The molecule on the left cannot be superimposed on the one on the right, and so these two molecules are distinct optical isomers. 

Figure 15.9 Two chiral molecules. A, 3-Methylhexane is chiral because C-3 is bonded to four different groups. These two models are optical isomers (enantiomers). B, The central C in the amino acid alanine is also bonded to four different groups.

Some of the physical and chemical properties of enantiomers are indistinguishable from one another. For example, both of the optical isomers of 3-methylhexane have identical freezing points, melting points, and densities. However, the properties of enantiomers differ from one another in two important ways (1) in the direction in which they rotate polarized light and (2) in their chemical behavior in a chiral environment.

Ordinary straight heptane has no optical activity, but one of the central carbon atoms in 3-methylhexane is circled because it has four different groups attached to it. It is this asymmetric arrangement around that carbon atom which causes the molecule to form a pair of optically active isomers. The pair of isomers are mirror images of each other.
