Which is the monomer of neoprene in the following?

Options

A. `CH_(2)=CH-CH-=CH`
B. `CH_(2)=underset(CH_(3))underset(|)(C)-CH=CH_(2)`
C. `CH_(2)=underset(Cl)underset(|)(C)-CH=CH_(2)`
D. `CH_(2)=CH-CH=CH_(2)`

Answer

C

Explanation

Neoprene is synthetic rubber and is a polymer of chloroprene which is chemically 2-chlorobuta-1, 3-diene
`underset("2-chloro-1, 3-butandiene(Chloroprene)")(nCH_(2)-underset(Cl)underset(|)(C)-CH-CH_(2))to underset("Neoprene")([--CH_(2)-underset(C) underset(|)(C)=CH-CH_2--]_(n))`
