The monomers of biodegradable polymer , nylon 2-nylon 6 are

Options

A. glycine + adipic acid
B. glycol +phthalic acid
C. phenol + urea
D. glycine + amino caproic acid .

Explanation

To determine the monomers of the biodegradable polymer nylon 2-nylon 6, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Biodegradable Polymers**:
- Biodegradable polymers are those that can be broken down into natural byproducts like carbon dioxide, nitrogen, water, and biomass through bacterial decomposition.

2. **Identify the Polymer in Question**:
- The polymer we are focusing on is nylon 2-nylon 6, which is a type of biodegradable polymer.

3. **Identify the Monomers**:
- The monomers that combine to form nylon 2-nylon 6 are glycine and amino caproic acid.
- Glycine has the chemical formula NH2CH2COOH.
- Amino caproic acid has the chemical formula NH2(CH2)5COOH.

4. **Reaction Mechanism**:
- When glycine and amino caproic acid react, they undergo a condensation reaction where a water molecule is removed.
- The reaction can be represented as follows:
- n NH2CH2COOH (glycine) + n NH2(CH2)5COOH (amino caproic acid) → nylon 2-nylon 6 + n H2O.

5. **Conclusion**:
- Therefore, the correct answer to the question regarding the monomers of biodegradable polymer nylon 2-nylon 6 is **glycine and amino caproic acid**.

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