Question

Which polymer has 'chiral' monomer(s)?

Options

• Neoprene 

• Buna - N 

• Nylon 6, 6

• PHBV

Answer 1

PHBV

Explanation:

\[\begin{array}{cc}\ce{OH}\phantom{.........}\\
|\phantom{...........}\\\ce{CH3 \underset{(3-Hydroxybutanoic acid)}{- CH - CH2 - COOH}}\end{array}\] and \[\begin{array}{cc}
\ce{OH}\\|\\\ce{CH3 - \underset{(3 - Hydroxypentanoic acid)}{CH2 - CH - CH2 - COO}H}\end{array}\]

Both monomers of PHBV have chiral centre.
