A) cis-isoprene
B) trans-isoprene
C) co-cis and trans isoprene
D) None of the above
Correct Answer: A
Solution :
Natural rubber is a polymer of cis-isoprene. \[\underset{cis-isoprene}{\mathop{nC{{H}_{2}}=\underset{\begin{smallmatrix} | \\ C{{H}_{3}} \end{smallmatrix}}{\mathop{C}}\,-CH-C{{H}_{2}}}}\,\xrightarrow{polymerisation}\] \[\underset{\begin{smallmatrix} poly\text{ }cis\text{ }isoprene \\ (natural\text{ }rubber) \end{smallmatrix}}{\mathop{-\left( C{{H}_{2}}-\underset{\begin{smallmatrix} | \\ C{{H}_{3}} \end{smallmatrix}}{\mathop{C}}\,=CH-C{{H}_{2}} \right)-}}\,\] OrYou need to login to perform this action.
