CC 13.2


→ Fig. 13.4 The application of sex pheromones in insect control involves using a small amount of synthetically produced pheromone to lure a particular insect into a trap.

← Fig. 13.7 A physical-state summary for unbranched 1-alkenes and unsubstituted cycloalkenes with one double bond at room temperature and pressure.



→ Fig. 13.8 In an alkene addition, reaction, the atoms provided by an incoming molecule are attached to the carbon atoms originally joined by a double bond. In the process, the double bond becomes a single bond.



← CC 13.3Carotenoids, molecules that contain eight isoprene units, are responsible for the yellow-orange color of autumn leaves.
