Question

Which polymer has chiral, monomer(s)?

• A. Buna-N
• B. Neoprene
• C. Nylon $6,6$
• D. PHBV

Answer 1

The correct option is D

PHBV

The correct option is (d)

The explanation is correct option is:

(d) PHBV

• Explanation: A polyhydroxyalkanoate-type polymer, PHBV stands for polyhydroxyalkanoate-type polymer. It's a biodegradable, nontoxic, biocompatible plastic made by bacteria, and it's a good substitute for several non-biodegradable synthetic polymers. It's a linear aliphatic polyester that's thermoplastic.
• Copolymerization of $3-$hydroxybutanoic acid and $3-$hydroxypentanoic acid produces it. Specialty packaging, orthopedic devices, and controlled drug release all use PHBV. In the environment, PHBV is degraded by bacteria.

The explanation for the incorrect option:

(a) Buna-N

• Explanation: Buna-N, commonly known as Nitrile rubber, NBR, or Perbunan, is a chiral monomer that does not fit within the category of polymer (s)

(b) Neoprene

• Explanation: Neoprene (also polychloroprene) is a group of synthetic rubbers made by polymerizing chloroprene. It is not a chiral polymer, but rather a monomer (s)

(c) Nylon $6,6$

• Explanation: Nylon$6,6$ is a form of polyamide or nylon that is mostly utilized in the textile and plastic industries. It is not classified as a polymer since it lacks chirality (s)

Hence option (d) is correct: PHBV polymer has chiral, monomer
