Which one of the following monomers gives the polymer neoprene on polymerization : -Neoprene is a synthetic rubber formed by free radical polymerisation of chloroprene (2-chlorobuta-1,3-diene), $CH_2=C(Cl)-CH=CH_2$:
$n\,CH_2=C(Cl)-CH=CH_2 \rightarrow [-CH_2-C(Cl)=CH-CH_2-]_n$
Neoprene is resistant to oils and is used to make conveyor belts, gaskets and hoses.
$CH_2=CHCl$ gives PVC and $CF_2=CF_2$ gives Teflon.
So the monomer of neoprene is $CH_2=C(Cl)-CH=CH_2$.
