Question:
Which of the following is a polyamide polymer?
Which of the following is a polyamide polymer?
Show Hint
A polyamide has repeating amide links in the chain. Think of the polymer made from a diamine and a diacid.
Updated On: Nov 12, 2026
- Nylon-6,6
- Teflon
- Bakelite
- Polythene
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
A polyamide contains repeating \(-\text{CONH}-\) linkages in its chain.
Step 2: Identify
Nylon-6,6 is made from hexamethylenediamine and adipic acid, joined through amide bonds.
Step 3: Why the other options fail
Teflon (C-C and C-F bonds) and polythene (C-C bonds) are addition polymers. Bakelite is a phenol-formaldehyde resin without amide groups.
Final Answer:
Nylon-6,6 is the polyamide. \[ \boxed{\text{(A) }\text{Nylon-6,6}} \]
