Question

Which one of the following monomers form biodegradable polymer?

• A. Urea and formaldehyde
• B. Ethylene glycol and terephthalic acid
• C. $3$-hydroxybutanoic acid and $3$-hydroxypentanoic acid
• D. Phenol and caproic acid

Answer 1

Answer: (C)

$3$-hydroxybutanoic acid and $3$-hydroxypentanoic acid

Answer 2

3-hydroxybutanoic acid and 3-hydroxypentanoic acid are the monomer unit of PHBV (poly- $\beta$-hydroxybutyrate-co-$\beta$-hydroxyvalerate). P HBV is biodegradable polymers and can be degraded by microorganisms within a suitable period.
