Question

Identify the monomers used in preparation of Nylon 2-nylon 6.

• A. Glycine and $\epsilon$-amino caproic acid
• B. $\beta$-hydroxy butyric acid and $\beta$-hydroxy valeric acid
• C. Ethylene glycol and phthalic acid
• D. Acrylamide and vinyl chloride

Hint:

Polymer nomenclature is heavily carbon-based. Nylon-6,6 uses two 6-carbon monomers (hexamethylenediamine and adipic acid). Nylon 2-nylon 6 uses a 2-carbon monomer and a 6-carbon monomer.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Nylon 2-nylon 6 is a biodegradable polyamide copolymer.

Step 2: Formula Application:
The numbers "2" and "6" represent the number of carbon atoms in each monomer.

Step 3: Explanation:
- Glycine ($H_2N-CH_2-COOH$) has 2 carbon atoms. - $\epsilon$-amino caproic acid ($H_2N-(CH_2)_5-COOH$) has 6 carbon atoms. Together, they form the alternating unit that gives the polymer its name. Option (b) describes PHBV, not Nylon.

Step 4: Final Answer:
The monomers are Glycine and $\epsilon$-amino caproic acid.
