- Styrene and glycolic acid
- Lactic acid and glycolic acid
- 3-Hydroxy butanoic acid and 3-hydroxy pentanoic acid
- Glycine and ω-amino caproic acid
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding PHBV polymer.
PHBV (Poly(3-hydroxybutyrate-co-3-hydroxyvalerate)) is a biopolymer composed of two monomers: 3-hydroxybutanoic acid and 3-hydroxyvaleric acid. These monomers are used in the preparation of PHBV polymer, which is biodegradable and used in various applications.
Step 2: Analyzing the options.
(A) Styrene and glycolic acid: These are not the monomers used for PHBV.
(B) Lactic acid and glycolic acid: This combination forms polylactic acid (PLA), not PHBV.
(C) 3-Hydroxy butanoic acid and 3-hydroxy pentanoic acid: These are the correct monomers used in the preparation of PHBV.
(D) Glycine and ω-amino caproic acid: These are not used for PHBV preparation.
Step 3: Conclusion.
The correct answer is (C) 3-Hydroxy butanoic acid and 3-hydroxy pentanoic acid.
