Q. Which is the monomer of neoprene in the following?
A) CH₂=CH–CH=CH₂
B) CH₂=C(CH₃)–CH=CH₂
C) CH₂=C(Cl)–CH=CH₂
D) CH₂=CH–C≡CH
Explanation
[Solution from source] Neoprene is polychloroprene, made from chloroprene (2-chlorobuta-1,3-diene), CH₂=C(Cl)–CH=CH₂. Buta-1,3-diene is the monomer of polybutadiene/Buna rubbers and isoprene is the monomer of natural rubber. Answer (3).
