Question

The structure of Nylon-6 is :

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The Correct Option is C

Nylon-6 is a type of synthetic polymer made from a monomer called caprolactam. The polymerization involves a single type of monomer, which distinguishes it as a polyamide. The correct structure of Nylon-6 involves repeating units derived from the opening up of a caprolactam ring.

Let us analyze the given options to identify the correct structure of Nylon-6:

1. The monomer for Nylon-6 is caprolactam, which forms a linear polymer called polycaprolactam after the opening of its ring.
2. The repeating unit involves an amide linkage, denoted as -NH-(CH₂)₅-CO-.
3. In the given options, the correct structure should show this repeated chain.

Upon examining the options, the correct structure corresponds with the image that matches our description of the repeating unit of Nylon-6:

This image shows the structure with correct connectivity of atoms and bonds in Nylon-6.

In conclusion, the correct answer is the third option, which depicts the linear structure typical of Nylon-6.

Understanding the fundamental chemistry behind polymer structures, including repeating units and connections in polyamides like Nylon-6, can greatly aid in identifying such structures in various scenarios.
