Which of the following statements is false?
Which of the following statements is false?
Updated On: Apr 28, 2025
- Nylon-66 is an example of elastomer.
- The repeat unit in natural rubber is isoprene.
- Both starch and cellulose are polymers of glucose.
- Artificial silk is derived from cellulose.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Nylon-66 is not an elastomer; it is a synthetic polymer that belongs to the class of polyamides. Elastomers are polymers that possess rubber-like elasticity, such as natural rubber or synthetic rubbers like polyisoprene.
So, the correct option is (A): Nylon-66 is an example of elastomer.
