Question

Which of the following is a natural polymer?

• A. Cellulose
• B. Teflon
• C. Polyvinylchloride
• D. Neoprene rubber

Hint:

If it comes from a tree or an animal (like silk, wool, or wood), it's a natural polymer.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
A natural polymer is a large molecule (macromolecule) found in nature, typically produced by living organisms like plants and animals.
Step 2: Key Formula or Approach:
Distinguish between naturally occurring substances and those synthesized in a laboratory or factory (synthetic).
Step 3: Detailed Explanation:

Cellulose: Found in the cell walls of plants. It is a polymer of $\beta$-D-glucose units. It is a natural polymer.
Teflon (PTFE): A synthetic polymer used in non-stick cookware.
Polyvinylchloride (PVC): A synthetic plastic used in pipes.
Neoprene: A synthetic rubber produced by the polymerization of chloroprene.

Step 4: Final Answer:
Cellulose is the natural polymer.
