(a)
Interpretation:
The short segment of polymer of 3-hydroxybutyric acid (PHB) has to be drawn.
Concept introduction:
Monomers combine together to form polymers. Monomers are the repeating units of small molecules which link together to form polymers and the process is called as
Two types of polymers:
- Synthetic and biopolymers.
- DNA is an example for biopolymer and these type of polymers are synthesized by cells.
- Polymers synthesized by scientists are called
synthetic polymers and some examples are nylon, polyester etc.
Two types of synthetic polymers:
- Chain-growth
polymers or addition polymers and Step-growthpolymers or Condensation polymers. - Chain growth polymers are formed by the monomer addition to the end of a growing chain.
- Step-growth polymers are formed by combining monomers by removing small molecules of water or alcohol.
(b)
Interpretation:
The short segment of polymer biopol (PHBV) with alternating monomers has to be drawn.
