# Answer the following. Write the structure of isoprene and the polymer obtained from it. - Chemistry

Short Note

Write the structure of isoprene and the polymer obtained from it.

#### Solution

1) Isoprene:

$\begin{array}{cc}\ce{H2C = C - C = CH2}\\ |\phantom{....}|\\\ce{\underset{\text{(isoprene)}}{CH3 H}}\end{array}$

2) Polymer of isoprene (polyisoprene or natural rubber):

$\begin{bmatrix}\begin{array}{cc}\ce{H\phantom{............}}\ce{H}\\ |\phantom{.............}|\\\ce{- C - C = C - C -}\\ |\phantom{.....}|\phantom{....}|\phantom{....}|\\ \ce{H\phantom{...}} \ce{CH3\phantom{..}} \ce{H\phantom{...}} \ce{H}\end{array}\end{bmatrix}_\text{n}$

(polyisoprene/rubber)
