Question

Identify the polymer from following, that contains amide linkage

• A. Terylene
• B. PHBV
• C. Nylon-6,6
• D. Dextron

Hint:

All nylons are polyamides and contain the characteristic \(-\mathrm{CONH}-\) linkage.

Answer 1

The Correct Option is C

Step 1: Understanding amide linkage.
An amide linkage is represented by the functional group \( -\mathrm{CONH}- \), which is formed by the condensation of a carboxylic acid and an amine.

Step 2: Analyzing each option.
(A) Terylene: It is a polyester containing ester linkage (\(-\mathrm{COO}-\)), not amide linkage.
(B) PHBV: It is a biodegradable polyester and contains ester linkages.
(C) Nylon-6,6: It is a polyamide formed from hexamethylenediamine and adipic acid and contains amide linkages.
(D) Dextron: It is a polysaccharide and does not contain amide linkage.

Step 3: Conclusion.
Thus, Nylon-6,6 is the polymer that contains amide linkage.
