Biodegradable polymer which can be produced from glycine and aminocaproic acid is

Options

A. PHBV
B. Buna-N
C. Nylon 6,6
D. Nylon 2-nylon 6

Explanation

To solve the question regarding the biodegradable polymer that can be produced from glycine and aminocaproic acid, we can follow these steps:

### Step 1: Understand the components
Identify the two compounds mentioned in the question:
- Glycine: An amino acid with the formula NH2CH2COOH.
- Aminocaproic acid: An amino acid with the formula NH2(CH2)5COOH.

### Step 2: Identify the type of polymer
We are looking for a biodegradable polymer. Biodegradable polymers are those that can be broken down by the action of living organisms, typically through microbial action.

### Step 3: Analyze possible polymers
We need to analyze the options given in the question to find out which polymer can be synthesized from glycine and aminocaproic acid.

1. **PHBV (Poly-beta-hydroxy-butyrate-co-beta-hydroxy-valerate)**: This is a known biodegradable polymer, but it is made from different monomers (3-hydroxybutanoic acid and 3-hydroxypentanoic acid), not from glycine and aminocaproic acid. Therefore, it is not the answer.

2. **BUNAN**: This is a non-biodegradable polymer, so it cannot be the answer.

3. **Nylon-666**: This is also a non-biodegradable polymer, hence not the answer.

4. **Nylon-2-Nylon-6**: This polymer can be synthesized from glycine and aminocaproic acid. The reaction involves a condensation process where water is eliminated, forming peptide bonds between the amino acids.

### Step 4: Synthesis of Nylon-2-Nylon-6
The reaction can be summarized as follows:
- Glycine (NH2CH2COOH) and Aminocaproic acid (NH2(CH2)5COOH) undergo a condensation reaction.
- During this reaction, an -OH group from the carboxylic acid of one amino acid and an -H from the amine of the other amino acid are removed, forming a peptide bond and releasing water.

The repeating unit of Nylon-2-Nylon-6 will consist of the structure formed by these two amino acids, making it a biodegradable polymer.

### Conclusion
The biodegradable polymer that can be produced from glycine and aminocaproic acid is **Nylon-2-Nylon-6**.

### Final Answer
**Nylon-2-Nylon-6**
