Nylon-6 is made from

Options

A. 1, 3-Butadiene
B. Chloroprene
C. Adipic acid
D. Caprolactum

Explanation

### Step-by-Step Solution:

1. **Identify the Polymer**: The question asks about Nylon-6, which is a type of synthetic polymer.

2. **Determine the Monomer**: To find out what Nylon-6 is made from, we need to identify its monomer. The monomer for Nylon-6 is caprolactam.

3. **Understanding Caprolactam**: Caprolactam is a cyclic amide with a structure that contains six carbon atoms. Its chemical formula is C6H11NO.

4. **Structure of Caprolactam**: The structure of caprolactam can be represented as:
- It has a cyclic structure with the following arrangement:
- CH2-CH2-CH2-CH2-CH2-CO-NH (where the nitrogen is part of the cyclic structure).

5. **Polymerization Process**: During the polymerization process, the ring structure of caprolactam opens up, allowing the molecules to link together to form a long chain, which is Nylon-6.

6. **Representation of Nylon-6**: In the polymerization reaction, the structure of Nylon-6 can be represented as:
- -[NH-(CH2)5-CO]-n (where "n" indicates the number of repeating units).

7. **Significance of the Number 6**: The "6" in Nylon-6 indicates that the polymer is derived from a monomer that contains six carbon atoms.

8. **Conclusion**: Therefore, the correct answer to the question "Nylon-6 is made from" is caprolactam.

### Final Answer:
Nylon-6 is made from caprolactam.
