Monomers of nylon 2-nylon 6 are-

Options

A. Glycine and glycerol
B. Glycine and amino caproic acid
C. Glycine and caprolactum
D. Hexamethylene diamine and adipic acid

Answer

To determine the monomers of nylon 2 and nylon 6, we need to identify the specific compounds that are used to synthesize these polymers through condensation polymerization.

### Step-by-Step Solution:

1. **Identify the Monomers**:
- Nylon 2 is formed from glycine, which is an amino acid. Its structure is:
\[ \text{Glycine: } \text{NH}_2\text{CH}_2\text{COOH} \]
- Nylon 6 is formed from amino caproic acid (also known as 6-aminocaproic acid). Its structure is:
\[ \text{Amino Caproic Acid: } \text{NH}_2\text{(CH}_2\text{)}_5\text{COOH} \]

2. **Understand the Polymerization Process**:
- The process of forming nylon 2 and nylon 6 involves condensation polymerization, where water is eliminated as the monomers react to form the polymer chain.
- The reaction can be summarized as:
\[ \text{Glycine} + \text{Amino Caproic Acid} \rightarrow \text{Nylon 2, Nylon 6} + \text{H}_2\text{O} \]

3. **Write the Structure of the Polymers**:
- The resulting polymer, nylon 2, will have a repeating unit that includes the amide linkages formed from the reaction of glycine and amino caproic acid:
\[ \text{Nylon 2, Nylon 6: } \text{...NH-CH}_2\text{CO-...NH-(CH}_2\text{)}_5\text{CO-...} \]

4. **Count the Carbon Atoms**:
- In nylon 2, there are 2 carbon atoms from glycine and 1 carbon from the amino caproic acid, totaling 2 carbon atoms.
- In nylon 6, there are 5 carbon atoms from the amino caproic acid and 1 carbon from glycine, totaling 6 carbon atoms.

5. **Conclusion**:
- Therefore, the correct monomers for nylon 2 and nylon 6 are glycine and amino caproic acid.

### Final Answer:
The monomers of nylon 2 and nylon 6 are glycine and amino caproic acid.
