Question

Write the equation for the laboratory preparation of ethene from iodoethane.

Answer 1

Laboratory preparation of Ethene from Iodoethane.

Ethene (${\mathrm{CH}}_2={\mathrm{CH}}_2$) can be obtained from Iodoethane (${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{I}$) by using the following reaction

$\underset{\mathrm{Iodoethane}}{{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{I}}+\underset{\mathrm{Potassium}\mathrm{hydroxide}}{\mathrm{KOH}\left(\mathrm{g}\right)}\to \underset{\mathrm{Ethene}}{{\mathrm{CH}}_2={\mathrm{CH}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Potassium}\mathrm{iodide}}{\mathrm{KI}\left(\mathrm{s}\right)}+\underset{\mathrm{Water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$
