Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding PHBV.
Polyhydroxybutyrate-co-hydroxyvalerate (PHBV) is a biodegradable plastic polymer obtained from the copolymerization of 3-hydroxybutanoic acid and 3-hydroxyvaleric acid (or 3-hydroxy pentanoic acid). It is synthesized through bacterial fermentation.
Step 2: Analyzing the options.
(A) PHBV: Correct — PHBV is the polymer made from these two monomers.
(B) Dextron: Incorrect — Dextron is a different polymer.
(C) Nylon-2-nylon-6: Incorrect — Nylon-2-nylon-6 is not made from these monomers.
(D) HDPE: Incorrect — HDPE is made from ethylene, not the given monomers.
Step 3: Conclusion.
The correct answer is (A) PHBV, as it is formed from 3-hydroxybutanoic acid and 3-hydroxy pentanoic acid.
