Question
The alkene is named (Z) if the two highest-priority substituents on each carbon are on the s____ sides
Answer
The alkene is named (Z) if the two highest-priority substituents on each carbon are on the same side of the double bond and (E) if they are on opposite sides
Note: The alkene is named (Z) (German: zusammen, “together”) if the two highest-priority substituents on each carbon are on the same side of the double bond and (E) (entgegen, “opposite”) if they are on opposite sides, as shown in Figure 2.15.
Note: Chirality can also be thought of as handedness. In fact, one of the easiest visualizations of chirality is to think of your own hands, as shown in Figure 2.9. Although essentially identical, your left hand will not be able to fit into a right-handed glove.
Note: A simple 180° rotation around a vertical axis, as shown in Figure 2.11, allows the compound to be superimposed upon its mirror image.
Note: For example, the C-1 carbon atom in 1-bromo-1-chloroethane has four different substituents. As shown in Figure 2.10, this molecule is chiral because it is not superimposable on its mirror image.
