Which of the following polymer is a polyamide ?
Show Hint
- Terylene
- Nylon
- Rubber
- Vulcanised rubber
The Correct Option is B
Solution and Explanation
Nylon (nylon-6,6 from hexamethylenediamine and adipic acid, or nylon-6 from caprolactam) has repeating \(\mathrm{-CO{-}NH-}\) amide links: a polyamide.
Natural rubber is a polymer of isoprene and vulcanised rubber is cross-linked rubber (sulphur bridges); neither contains amide groups.
Answer: (2) Nylon

Top JEE Main Questions
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
