Nylon-6, is is formed by heating

Options

A. Adipic acid and methane
B. Succinic acid and 1,3-butadiene
C. adipie acid and hexamethytene
D. None

Answer

To answer the question regarding the formation of Nylon-6, we need to analyze the options given and understand the chemistry behind Nylon-6.

### Step-by-Step Solution:

1. **Understanding Nylon-6**:
- Nylon-6 is a type of synthetic polymer known as a polyamide. It is formed through the polymerization of a specific monomer called caprolactam.

2. **Identifying Caprolactam**:
- Caprolactam is a cyclic amide (lactam) with the chemical formula C6H11NO. It contains a nitrogen atom in its structure, which is crucial for the formation of the polyamide.

3. **Evaluating the Options**:
- The options provided are:
a) Adipic acid and methane
b) Succinic acid and 1,3-butadiene
c) Adipic acid and hexamethylene
d) None of the above
- We need to determine if any of these combinations can produce caprolactam.

4. **Analyzing Each Option**:
- **Option a**: Adipic acid and methane do not yield caprolactam.
- **Option b**: Succinic acid and 1,3-butadiene also do not lead to caprolactam.
- **Option c**: Adipic acid and hexamethylene do not produce caprolactam either.
- Since none of these combinations yield caprolactam, they cannot form Nylon-6.

5. **Conclusion**:
- Since none of the options provided lead to the formation of caprolactam, the correct answer is option d) None of the above.

### Final Answer:
Nylon-6 is formed from caprolactam, and thus the correct answer is **d) None of the above**.
