The correct Answer is:
To solve the question regarding the copolymerization that leads to the formation of Poly Beta-hydroxybutyrate-co-Beta-hydroxy valerate (PHBV), we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Components**: - PHBV is a copolymer, which means it is made from two different monomers. - The two monomers involved in the formation of PHBV are 3-hydroxybutanoic acid and 3-hydroxyvaleric acid. 2. **Identifying the Monomers**: - 3-hydroxybutanoic acid (also known as beta-hydroxybutyric acid) is the first monomer. - 3-hydroxyvaleric acid (also known as beta-hydroxyvaleric acid) is the second monomer. 3. **Copolymers Formation**: - The copolymerization process involves the reaction of these two monomers under specific conditions (usually involving heat and/or catalysts) to form a polymer chain that incorporates both types of monomers. 4. **Final Structure**: - The resulting polymer, PHBV, contains repeating units derived from both 3-hydroxybutanoic acid and 3-hydroxyvaleric acid, which contributes to its properties and applications. 5. **Applications of PHBV**: - PHBV is used in various applications such as packaging materials, orthopedic devices, and in the controlled release of drugs due to its biodegradable nature. ### Final Answer: Poly Beta-hydroxybutyrate-co-Beta-hydroxy valerate (PHBV) is obtained by the copolymerization of 3-hydroxybutanoic acid and 3-hydroxyvaleric acid.
