Question

Give the products formed when

When ethyl chloride is treated with alcoholic$\mathrm{KOH}$ __________.

Answer 1

1. Ethyle chloride is chemically represented as ${\mathbf{CH}}_{\mathbf{3}}\mathbf{-}{\mathbf{CH}}_{\mathbf{2}}\mathbf{-}\mathbf{Cl}$.
2. When Ethyl chloride$\left({\mathrm{CH}}_3-{\mathrm{CH}}_2-\mathrm{Cl}\right)$ reacts with alcoholic $\mathrm{KOH}$the elimination of Hydrogen chloride takes place
3. The chemical reaction is as follows:$\underset{(\mathrm{Ethyl}\mathrm{chloride})}{{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{Cl}\left(\mathrm{g}\right)}+\underset{(\mathrm{Potassium}\mathrm{hydroxide})}{\mathrm{KOH}\left(\mathrm{aq}\right)}\to \underset{\left(\mathrm{Ethene}\right)}{{\mathrm{C}}_2{\mathrm{H}}_4\left(\mathrm{g}\right)}+\underset{(\mathrm{Potassium}\mathrm{chloride})}{\mathrm{KCl}\left(\mathrm{s}\right)}+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$
4. The formation of Ethene$\mathbf{\left(}{\mathbf{C}}_{\mathbf{2}}{\mathbf{H}}_{\mathbf{4}}\mathbf{\right)}$ gas takes place which is colorless, inflammable gas and are having faint smell.
5. Hence, we concluded that when Ethyl chloride$\left({\mathrm{CH}}_3-{\mathrm{CH}}_2-\mathrm{Cl}\right)$ is treated with alcoholic $\mathrm{KOH}$then Ethene is formed as gas.
