Question:
Which of the following polymers is NOT semisynthetic?
Which of the following polymers is NOT semisynthetic?
Show Hint
Semisynthetic polymers are made by chemically modifying natural polymers such as cellulose.
Updated On: Nov 12, 2026
- Cellulose acetate rayon
- Cuprammonium rayon
- Teflon
- Cellulose nitrate
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
A semisynthetic polymer is obtained when a natural polymer is chemically modified.
Step 2: Cellulose derivatives
Cellulose acetate rayon, cuprammonium rayon and cellulose nitrate are all prepared from natural cellulose, so they are semisynthetic.
Step 3: Teflon
Teflon is made by addition polymerisation of tetrafluoroethene, \(\text{CF}_2\text{=CF}_2\). It is fully synthetic.
Step 4: Compare the options
Teflon is the one that is not semisynthetic.
Final Answer:
Teflon is not a semisynthetic polymer. \[ \boxed{\text{(C) }\text{Teflon}} \]
