Q. Which of the following structures represents Neoprene polymer?
A) [–CH(C₆H₅)–CH₂–]ₙ
B) [–CH₂–C(Cl)=CH–CH₂–]ₙ
C) [–CH₂–CH(CN)–]ₙ
D) [–CH₂–CH(Cl)–]ₙ
Explanation
[Solution from source] Neoprene is polychloroprene, made from chloroprene (2-chloro-1,3-butadiene): [–CH₂–C(Cl)=CH–CH₂–]ₙ. The –CH(C₆H₅)– polymer is polystyrene, –CH(CN)– is polyacrylonitrile and –CH(Cl)– is PVC. Answer (2).
