Which of the following statements is correct?

Options

A. Caprolactum is the monomer of nylon 6,6
B. Terylene is a polyamide
C. Phenol formaldehyde resin is known as bakelite
D. Butadiene is not the monomer of natural rubber

Answer

To determine which of the statements is correct, we will analyze each option step by step.

### Step 1: Analyze the first statement
**Statement:** Caprolactam is a monomer of nylon 6-6.

- **Explanation:** Caprolactam is actually the monomer used to produce nylon 6, not nylon 6-6. Nylon 6-6 is made from hexamethylenediamine and adipic acid. Therefore, this statement is **incorrect**.

### Step 2: Analyze the second statement
**Statement:** Terylene is a polyamide.

- **Explanation:** Terylene is made from the polymerization of terephthalic acid and ethylene glycol, which makes it a polyester, not a polyamide. Thus, this statement is also **incorrect**.

### Step 3: Analyze the third statement
**Statement:** Phenol and formaldehyde resin is Bakelite.

- **Explanation:** Bakelite is indeed a type of plastic that is produced from the polymerization of phenol and formaldehyde. This statement is **correct**.

### Step 4: Analyze the fourth statement
**Statement:** Butadiene is not the monomer of natural rubber.

- **Explanation:** Butadiene is actually the monomer used to produce natural rubber (polybutadiene). Therefore, this statement is **incorrect**.

### Conclusion
After analyzing all four statements, we find that the only correct statement is:

**Correct Statement:** Phenol and formaldehyde resin is Bakelite.
