Caprolactam is used for the manufacture of `:`

Options

A. nylon-6
B. teflon
C. terylene
D. nylon-6,6

Explanation

To solve the question regarding the use of caprolactam in the manufacture of polymers, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Caprolactam**:
- Caprolactam is a cyclic amide (lactam) with the chemical formula C6H11NO. It contains a carbonyl group (C=O) and an amine group (NH).

2. **Understand the Reaction**:
- When caprolactam is mixed with water, it undergoes hydrolysis, leading to the formation of an intermediate compound. This process involves the breaking of the lactam ring.

3. **Formation of the Intermediate**:
- The hydrolysis of caprolactam can be represented as:
\[ \text{N molecules of caprolactam} + \text{N molecules of water} \rightarrow \text{Intermediate} \]
- In this intermediate, the carbonyl group (C=O) and the amine group (NH) will be involved in forming new bonds with water.

4. **Polymerization Process**:
- The intermediate formed can further react to form long chains through a process called polymerization. During this process, the amine group of one intermediate reacts with the carbonyl group of another, leading to the formation of amide linkages.

5. **Final Polymer Structure**:
- The resulting polymer from this reaction is known as Nylon 6, which consists of repeating units of the amide linkages. The structure can be represented as:
\[ -[NH-(CH2)5-CO]- \text{ (repeating unit of Nylon 6)} \]

6. **Conclusion**:
- Therefore, caprolactam is specifically used for the manufacture of Nylon 6, which is a type of polyamide.

### Final Answer:
Caprolactam is used for the manufacture of Nylon 6.
