Question

The correct reactant pair for the formation of PHBV polymer is-

• A. \(3\)-hydroxybutanoicacid and \(3\)-hydroxypentanoicacid
• B. \(2\)-ethyl-\(3\)-hydroxybutanoicacid and \(3\)-hydroxybutanoicacid
• C. \(3\)-hydroxybutanoicacid and \(4\)-hydroxy-\(2\)-methylpentanoicacid
• D. \(3\)-hydroxy-\(2\)-methylbutanoicacid and \(4\)-hydroxy-\(3\)-methylpentanoicacid.

Hint:

PHBV is a copolymer of 3-hydroxybutanoic acid and 3-hydroxypentanoic acid.

Answer 1

The Correct Option is A

Step 1: Decode the Name
B stands for butyrate and V for valerate (pentanoate).

Step 2: Position
Both hydroxy groups are on the third carbon (beta position).

Step 3: Select
Option (A).

Final Answer:
The name PHBV points to option (A). \[ \boxed{\text{(A) }\text{3-hydroxybutanoic acid and 3-hydroxypentanoic acid}} \]
