NEET levelSingle correct optionDifficulty 1 of 3pl076

Neoprene is a polymer of

Achloroethene, $CH X_{2} = CHCl$
B1-chlorobuta-1,3-diene, $ClCH = CH - CH = CH X_{2}$
Ctetrafluoroethene, $CF X_{2} = CF X_{2}$
D2-chlorobuta-1,3-diene, $CH X_{2} = C (Cl) - CH = CH X_{2}$

Answer: D

Neoprene is formed by free-radical polymerisation of chloroprene, 2-chlorobuta-1,3-diene. Chloroethene gives PVC and tetrafluoroethene gives PTFE.
