Which is the monomer of neoprene in the following?

Options

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

Answer

B

Explanation

Neoprene is formed by the radical polymerization of chloroprence:
`nCH_(2)-C-underset(CI)underset(|)(CH)=CH_(2) rarr (CH_(2)-overset(CI)overset(|)(C)=CH-CH_(2))_(n)`
