Which amongst the following molecules on polymerization produces neoprene? 1. H₂C=C(CH₃)-CH=CH₂ 2. H₂C=CH-CH=CH₂ 3. H₂C=C(Cl)-CH=CH₂ 4. H₂C=CH-Cequiv CH

Answer: 3. H₂C=C(Cl)-CH=CH₂ Key idea: Neoprene is a polymer of chloroprene, 2-chlorobuta-1,3-diene. Chloroprene is CH₂=C(Cl)-CH=CH₂ , which is option 3. Option 1 (isoprene) gives natural rubber; option 2 (buta-1,3-diene) gives polybutadiene / Buna rubbers.
