Question

Complete the following reaction:

${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}+{\mathrm{PCl}}_5\to$

Answer 1

1. When we react alcohol with Phosphorous pentachloride then it generally forms alkyl halide.
2. When we react Ethyl alcohol with Phosphorous pentachloride then it forms Ethyl chloride, Phosphoryl chloride and Hydrochloric acid.
3. The chemical reaction is as follows:

$\underset{\left(\mathrm{Ethyl}\mathrm{alcohol}\right)}{{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}\left(\mathrm{l}\right)}+\underset{(\mathrm{Phosphorous}\mathrm{pentachloride})}{{\mathrm{PCl}}_5\left(\mathrm{s}\right)}\to \underset{(\mathrm{Ethyl}\mathrm{chloride})}{{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{Cl}\left(\mathrm{g}\right)}+\underset{(\mathrm{Phosphoryl}\mathrm{chloride})}{{\mathrm{POCl}}_3\left(\mathrm{l}\right)}+\underset{(\mathrm{Hydrochloric}\mathrm{acid})}{\mathrm{HCl}\left(\mathrm{l}\right)}$
