It is obtained by copolymerization of 1, 3-butadiene and styrene
It is obtained by copolymerization of 1, 3-butadiene and acrylonitrile
The suffix N in Buna-N stands for its natural occurrence.
Show Solution
The Correct Option isC
Solution and Explanation
Buna-N, also known as nitrile rubber, is a synthetic rubber used widely in the manufacturing of items that require good resistance to oils and fuels. Here is the detailed explanation regarding the options given:
It is a linear polymer of 1, 3-butadiene: This statement is incorrect. Buna-N is not a linear polymer of 1, 3-butadiene alone. It is a copolymer.
It is obtained by copolymerization of 1, 3-butadiene and styrene: This statement is incorrect. The copolymerization of 1, 3-butadiene and styrene produces a different synthetic rubber known as Buna-S or Styrene-Butadiene Rubber (SBR), not Buna-N.
It is obtained by copolymerization of 1, 3-butadiene and acrylonitrile: This statement is correct. Buna-N is indeed produced by the copolymerization of 1, 3-butadiene and acrylonitrile. The process creates a synthetic rubber with properties that make it highly resistant to oils, fuels, and other chemicals.
The suffix N in Buna-N stands for its natural occurrence: This statement is incorrect. The "N" in Buna-N stands for acrylonitrile, which is one of the monomers used in its formation, not for natural occurrence.
Conclusion: The correct answer is that Buna-N is obtained by the copolymerization of 1, 3-butadiene and acrylonitrile. This synthesis provides the material with its characteristic resistance properties, making it suitable for applications in various industries requiring durability against oils and chemicals.
