Q149 / 200 · MHT CET - Medical 2026 (21 April Shift 1) · Chemistry

Identify the polymer from the following that is obtained by using one of the $\alpha$-amino acids.

  • A
    Nylon-6
  • B
    PHBV
  • Correct answer
    C
    Nylon2- nylon6
  • D
    Bakelite

Solution

Nylon-2-nylon-6 is an alternating polyamide copolymer synthesized from glycine and aminocaproic acid.

Glycine ($H_2N-CH_2-COOH$) is an $\alpha$-amino acid, whereas aminocaproic acid ($H_2N-(CH_2)_5-COOH$) is an $\epsilon$-amino acid.

Nylon-6 is formed from caprolactam.

PHBV is formed from 3-hydroxybutanoic acid and 3-hydroxypentanoic acid.

Bakelite is formed from phenol and formaldehyde.

Thus, Nylon-2-nylon-6 is the polymer obtained by using an $\alpha$-amino acid.

Answer: Nylon2- nylon6

Hence, the correct answer is option: 'C'.
