Question

Which amongst the following molecules on polymerization produces neoprene?

पर्याय

• \[\begin{array}{cc}
  \ce{Cl}\phantom{........}\\
  |\phantom{.........}\\
  \ce{H2C = C - CH = CH2}
  \end{array}\]

• H₂C = CH – C = CH

• \[\begin{array}{cc}
  \ce{CH3}\phantom{.....}\\
  |\phantom{.........}\\
  \ce{H2C = C - CH = CH2}
  \end{array}\]

• H₂C = CH – CH = CH₂

Answer 1

\[\begin{array}{cc}
\ce{Cl}\phantom{........}\\
|\phantom{.........}\\
\ce{H2C = C - CH = CH2}
\end{array}\]

Explanation:

\[\begin{array}{cc}
\ce{Cl}\phantom{............................................................}\ce{Cl}\phantom{...............}\\
|\phantom{...............................................................}|\phantom{................}\\
\ce{\underset{Chloroprene}{CH2 = C - CH = CH2} ->[Temp and pressure] \underset{Neoprene}{-[CH2 - C = CH - CH2] -_n}}
\end{array}\]
