Option analysis
Believing Buna-S is a homopolymer because it forms via addition polymerization. Addition polymers can also be copolymers; Buna-S is synthesized from two different monomers: 1,3-butadiene and styrene.
None; this is the correct choice. Neoprene is prepared from a single monomer, chloroprene, making it a homopolymer rather than a copolymer.
Confusing biodegradability or condensation mechanism with being a homopolymer. PHBV is a copolymer of 3-hydroxybutanoic acid and 3-hydroxypentanoic acid.
Failing to recognize that butadiene-styrene rubber is synonymous with Buna-S and derived from two distinct monomers. The name directly indicates two distinct monomer units, butadiene and styrene, making it a copolymer.
Identify the homopolymer made of a single type of monomer. Examples include Neoprene (from chloroprene only) and Natural rubber (from isoprene only). Other examples are PAN, Teflon, and PVC. Each of these forms from just one monomer. In contrast, copolymers like Buna-S, Buna-N, Dacron, and Nylon-6,6 form from multiple monomers.
What distinguishes a copolymer from a homopolymer?
A copolymer is derived from two or more different types of monomers, whereas a homopolymer is derived from only one monomer type.Which of the listed polymers is prepared by polymerizing only a single monomer species?
Neoprene, which is formed solely from chloroprene (2-chloro-1,3-butadiene).
