Question

Which of the following monomers is used in the manufacture of Neoprene rubber?

पर्याय

• Styrene

• 2-Chlorobuta-1, 3-diene

• 1, 3-Butadiene

• lsobutylene

Answer 1

2-Chlorobuta-1, 3-diene

Explanation:

The monomer used is chloroprene (2-chlorobuta-1, 3-diene).

\[\begin{array}{cc}
\phantom{..}\ce{Cl}\phantom{.....................................}\ce{Cl}\phantom{..........}\\
\phantom{...}|\phantom{.......................................}|\phantom{...........}\\
\ce{\underset{2-chlorobuta-1, 3-diene}{{n} CH2 = C - CH = CH2} ->[oxygen of][benzoyl peroxide] \underset{Neoprene}{[- CH2 - C = CH - CH2 -]_{{n}}}}
\end{array}\]
