Nylon-`6`is prepared from:

Answer

To determine how Nylon-6 is prepared, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Monomer**:
- Nylon-6 is synthesized from a specific monomer known as caprolactam.

2. **Understand the Polymerization Process**:
- The process used to create Nylon-6 is called linear condensation polymerization. This involves the reaction of the monomer (caprolactam) to form the polymer (Nylon-6).

3. **Conditions for Polymerization**:
- To initiate the polymerization, caprolactam is heated with water. This reaction takes place under specific conditions:
- An inert atmosphere of nitrogen is maintained to prevent unwanted reactions.
- The temperature is set to approximately 533 Kelvin (which is around 260°C).
- The reaction is allowed to proceed for about 4 hours.

4. **Result of the Reaction**:
- After the reaction, Nylon-6 is formed as the end product from the polymerization of caprolactam.

### Final Answer:
Nylon-6 is prepared from caprolactam through linear condensation polymerization.
