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

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

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