Question:
Which of the following is not a semi-synthetic polymer?
Which of the following is not a semi-synthetic polymer?
Show Hint
Semi-synthetic polymers are derived from natural sources but chemically modified for enhanced properties.
Updated On: Mar 25, 2025
- Cis-polyisoprene
- Cellulose nitrate
- Cellulose acetate
- Vulcanised rubber
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding Semi-Synthetic Polymers
Semi-synthetic polymers are derived by chemically modifying natural polymers.
Examples include cellulose derivatives and modified rubber.
Step 2: Classification of Given Options
Cis-polyisoprene is natural rubber, not a semi-synthetic polymer.
Cellulose nitrate and Cellulose acetate are modified cellulose derivatives.
Vulcanized rubber is chemically treated natural rubber, making it semi-synthetic.
Final Answer: Since cis-polyisoprene is natural rubber, the correct answer is (A).
