Chemistry - Polymer Question with Solution | TestHub
Polymers are made of small molecules known as monomers. Homopolymer is that which is formed by only one type of monomer. copolymer is that which is formed by more than are type of monomers. Natural polymers are biodegradable where as synthetic polymers may or may not be. Cross linked polymers are always condensation polymers.
Which of the following is a copolymer
Options:
Answer:
Solution:
Question Explanation: Question asking about example of copolymer.
Concept: This question is based on more than one type of monomers.
Solution:
1. Polypropylene - Homopolymer of propene.
2. Bakelite - Copolymer of phenol and formaldehyde.
3. PVC - Homopolymer of vinyl chloride.
4. Polystyrene - Homopolymer of styrene.
Bakelite is the crosslinked, thermosetting, condensation copolymer of phenol and excess of formaldehyde.
Final answer: The correct option is (B).
