उत्तर
(a) Structural formula of ethene:
\[\begin{array}{cc}
\phantom{.......}\ce{H}\phantom{...}\ce{H}\phantom{........}\\
\phantom{...}\text{\\}\phantom{...} \phantom{.}\text{/}\phantom{....}\\
\ce{C = C}\\
\phantom{....}\text{/}\phantom{...}\phantom{.}\text{\\}\phantom{....}\\
\phantom{........}\ce{H}\phantom{...}\ce{H}\phantom{........}\\
\end{array}\]
(b) Ethene can react with chlorine because there is presence of double bond which can result in the addition reaction.
