Question

Which compound polymerisation to neoprene ?
A. `CH_(2)=CHCl `
B. `CH_(2)=C*CH-CH=CH_(2)`
C. `Cl_(2)C=C*Cl_(2)`
D. `F_(2)C=CF_(2)`

Answer 1

Correct Answer - B
Neoprene is a synthetic rubber. It is prepared by polymerisation of 2-chlorobuta-1, 3-diene .
`underset("Chloroprene")(nCH_(2)=underset(Cl)underset(|)(C)-CH) overset("Polymerisation")to underset("Neoprene")([--CH_(2)-underset(Cl)underset(|)(C)=CH-CH_(2)--]_(n)`
