Final answer:
The advantages of making complex molecules out of simple polymers include the ability to achieve a wide range of properties and the commercial advantages of being produced inexpensively. By selecting different monomer units, scientists can tailor the physical properties of synthetic polymers for specific purposes, making them more desirable than their natural counterparts.
Step-by-step explanation:
One advantage of making complex molecules out of simple polymers is that it allows for a wide range of properties to be achieved. By selecting different monomer units, scientists can tailor the physical properties of the resulting polymer for specific purposes. For example, plastics can be made more durable, lighter, and easier to shape and maintain compared to natural materials like wood. Another advantage is that synthetic polymers can be produced inexpensively, making them commercially advantageous over naturally occurring polymers. This has led to their widespread use in everyday life, from plastics to rubbers, adhesives to resistant paints.
