The biodegradable polymer is :

  1. nylon-6
  2. Buna-S
  3. nylon-6, 6
  4. nylon-2-nylon 6

Answer

(4) nylon-2-nylon 6

Solution

As per NCERT, nylon-2–nylon-6 is an alternating polyamide copolymer of glycine ( H2N-CH2-COOH) and amino caproic acid ( H2N-(CH2)5-COOH) and it is biodegradable.

Its amide linkages are broken down by enzymes, like those of proteins.

Nylon-6, nylon-6,6 and Buna-S are non-biodegradable.
