The biodegradable polymer obtained by polymerisation of Glycine and Aminocaproic acid is:
Show Hint
- Nylon 6
- PHBV
- Nylon 2 – Nylon 6
- Nylon 6, 10
The Correct Option is C
Solution and Explanation
The question asks about the biodegradable polymer obtained by the polymerization of Glycine and Aminocaproic acid. Let's break down the options and determine why the correct answer is Nylon 2 – Nylon 6.
Explanation:
- Biodegradable Polymers: These are polymers that can decompose naturally in the environment through the action of living organisms, typically bacteria.
- Polymerisation: It's a chemical reaction wherein monomers combine to form a polymer. In this question, the monomers involved are Glycine and Aminocaproic acid.
- Nylon 2–Nylon 6:
- This polymer is formed through the copolymerization of Glycine and Aminocaproic acid.
- Nylon 2 represents the repeat unit derived from Glycine, whereas Nylon 6 represents the repeat unit derived from Aminocaproic acid.
- \([\text{Glycine} (NH_2CH_2COOH) + \text{Aminocaproic acid} (NH_2(CH_2)_5COOH)]\rightarrow[-NHCH_2CO-NH(CH_2)_5CO-]_n\)
- This polymer is classified as biodegradable because it breaks down over time through natural processes due to the presence of peptide-like bonds, which are susceptible to enzymatic action.
Elimination of Other Options:
- Nylon 6: This is a synthetic polymer formed from caprolactam, and it is not biodegradable due to its strong inter-chain hydrogen bonding and crystalline nature.
- PHBV: Polyhydroxybutyrate-co-valerate is indeed a biodegradable polymer, but it is derived from hydroxy acids rather than Glycine and Aminocaproic acid.
- Nylon 6, 10: This polymer is formed from hexamethylenediamine and sebacic acid, making it unsuitable as an answer because it involves completely different monomers.
Conclusion: The only option that matches the criteria and is formed from Glycine and Aminocaproic acid as described is Nylon 2 – Nylon 6.
