Question:
Which of the following monomer is used for preparation of Nylon-6?
Which of the following monomer is used for preparation of Nylon-6?
Show Hint
Nylon-6,6 requires two different 6-carbon monomers (hexamethylenediamine and adipic acid), but Nylon-6 requires only one 6-carbon cyclic monomer, which is caprolactam.

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Question:
We need to identify the single monomer starting material used to synthesize the polymer Nylon-6.
Step 2: Detailed Explanation:
Nylon-6 is a synthetic polyamide polymer.
It is synthesized by heating caprolactam with water at a high temperature (around $533\text{-}543\ \text{K}$).
Under these conditions, the seven-membered caprolactam ring opens up to form aminocaproic acid, which then undergoes continuous condensation polymerization to form the long chains of Nylon-6.
The "6" in its name specifically indicates that the monomer, caprolactam, contains exactly six carbon atoms.
Step 3: Final Answer:
The monomer used is caprolactum, matching option (C).
