Select the correct option to match the Polymer to its most suitable Monomer(s) from the table given below:
Answer: A
The correct matching is P-II ; Q-IV ; R-III ; S-I.
- Poly(p-phenylene sulfide) is made from sodium sulfide and p-dichlorobenzene, joining benzene rings through sulfur (II).
- Poly(ether sulfone) comes from the self-condensation of 4-chloro-4'-hydroxydiphenyl sulfone, which forms ether links between sulfone units (IV).
- PEEK is made from 4,4'-difluorobenzophenone and hydroquinone, giving two ether links and one ketone per repeat unit (III).
- Polycarbonate is made from phosgene and bisphenol A (I).
The other options assign the sulfone-containing monomer to PEEK or the phosgene route to a sulfide or sulfone polymer, which does not give the named backbone.
