Question

Give the balanced equation for the laboratory preparation of an alcohol from Ethyl bromide.

Answer 1

Laboratory preparation of an alcohol from Ethyl bromide

• Alcohols are prepared in the laboratory by the hydrolysis of alkyl halides.
• Alkyl halides are treated with Sodium hydroxide$\left(NaOH\right)$ or Potassium hydroxide$\left(KOH\right)$ to give alcohol.
• In this reaction, Ethyl bromide$\left(C_2{H}_{5}Br\right)$ is treated with Sodium hydroxide.
• The balanced chemical reaction is given below:

$\underset{(\mathrm{Ethyl}\mathrm{bromide})}{{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{Br}\left(\mathrm{g}\right)}+\underset{(\mathrm{Sodium}\mathrm{hydroxide})}{\mathrm{NaOH}\left(\mathrm{aq}\right)}\to \underset{\left(\mathrm{Ethanol}\right)}{{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}\left(\mathrm{l}\right)}+\underset{(\mathrm{Sodium}\mathrm{bromide})}{\mathrm{NaBr}\left(\mathrm{s}\right)}$
