Excess of hydrochloric acid

Answer 1

Ethyne reacts with hydrochloric acid to first form chloroethene and finally 1, 1-dichloroethane.

\[\begin{array}{cc}
\ce{CH ->[+HCl] CH2 ->[+HCl] CH3}\\
\phantom{}|||\phantom{.........}||\phantom{...........}|\phantom{....}\\
\phantom{......}\ce{\underset{Ethyne}{CH}}\phantom{.....}\ce{\underset{Chloroethene}{CHCl}}\phantom{.}\ce{\underset{1, 1-dichloroethane}{CHCl2}}\phantom{..}
\end{array}\]
