Which compound polymerisation to neoprene ?

A

`CH_(2)=CHCl `

B

`CH_(2)=C*Cl-CH=CH_(2)`

C

`Cl_(2)C=C*Cl_(2)`

D

`F_(2)C=CF_(2)`

Text Solution

Verified by Experts

The correct Answer is:
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)`
