Question

Which of the following is a natural polymer?

• A. Cellulose
• B. Nylon-6
• C. PVC
• D. Teflon

Hint:

Remember that natural polymers are derived from biological sources, whereas synthetic polymers are produced through chemical reactions.

Answer 1

The Correct Option is A

Step 1: Natural versus synthetic.
A natural polymer is found in nature, made by plants or animals. A synthetic polymer is man made in a factory.
Step 2: Look at cellulose.
Cellulose is found in the cell walls of plants. It is made from many glucose units joined together, so it is a natural polymer.
Step 3: Look at Nylon-6.
Nylon-6 is made in a factory from caprolactam. So it is a synthetic polymer, not natural.
Step 4: Look at PVC.
PVC is made by joining vinyl chloride units in a plant. So it is also synthetic.
Step 5: Look at Teflon.
Teflon is made by joining tetrafluoroethylene units. It too is a man made synthetic polymer.
Step 6: Final choice.
Only cellulose comes from nature, so it is the natural polymer.\[ \boxed{\text{Cellulose}} \]
