Question

State how the conversion can be carried out from Ethyl chloride to Ethene

Answer 1

• Ethyl chloride ($C_2{H}_{5}Cl$) on treatment with alcoholic Potassium hydroxide ($KOH$) gives Ethene and Hydrochloric acid ($HCl$) as the products.
• The chemical Reaction is as follows.

$\underset{\mathrm{Ethyl}\mathrm{chloride}}{{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{Cl}\left(\mathrm{l}\right)}+\underset{\mathrm{Potassium}\mathrm{hydroxide}}{\mathrm{KOH}\left(\mathrm{s}\right)}\to \underset{\mathrm{Ethene}}{{\mathrm{CH}}_2={\mathrm{CH}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Hydrochloric}\mathrm{acid}}{\mathrm{HCl}\left(\mathrm{g}\right)}$

• It is an example for elimination reaction.
