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

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)
