Vedclass · Answer

(A) The copolymer formed by the condensation polymerization of $3$-hydroxybutanoic acid ($\beta$-hydroxybutyric acid) and $3$-hydroxypentanoic acid ($\beta$-hydroxyvaleric acid) is known as Poly-$\beta$-hydroxybutyrate-co-$\beta$-hydroxyvalerate, abbreviated as $PHBV$.
The reaction is:
$n(HO-CH(CH_3)-CH_2-COOH) + n(HO-CH(CH_2CH_3)-CH_2-COOH)$ $\rightarrow [-O-CH(CH_3)-CH_2-CO-O-CH(CH_2CH_3)-CH_2-CO-]_n + 2nH_2O$
Thus, the correct option is $A$.

Identify a polymer obtained from $\beta$-hydroxybutyric acid and $\beta$-hydroxyvaleric acid.
