Question

Find monomers of PHBV.

• A. \(\beta\) - hydroxy Butyric acid and \(\beta\) - hydroxy Valeric acid
• B. Glycine and \(\epsilon\) amino caproic acid
• C. \(\alpha\) - hydroxy Butyric acid and \(\beta\) - hydroxy Valeric acid
• D. \(\beta\) - hydroxy Butyric acid and caproic acid

Hint:

PHBV is poly(3-hydroxybutyrate-co-3-hydroxyvalerate).

Answer 1

The Correct Option is A

Step 1: Eliminate
Glycine with amino caproic acid gives Nylon-2-nylon-6.

Step 2: Check the others
Options with alpha-hydroxy or caproic acid do not match the name PHBV.

Step 3: Conclude
The name has hydroxybutyrate and hydroxyvalerate parts, both at the beta position, so the first option fits.

Final Answer:
PHBV is formed from the two beta-hydroxy acids. \[ \boxed{\text{(A) }\beta\text{-hydroxy butyric acid and }\beta\text{-hydroxy valeric acid}} \]
