Question

Explain one property of Ethanol

Answer 1

Ethanol:

• Ethanol is a compound of carbon, hydrogen, and oxygen elements.
• Ethanol can be found naturally as a plant fermentation by-product and it can also be produced during the hydration of ethene.
• Ethanol formula can be represented as ${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}$.
• At room temperature ethanol is always a liquid.
• It has a melting point of $156\mathrm{K}$ and a boiling point of $351\mathrm{K}$.
• Ethanol is Soluble in water.
• When Ethanol is heated at $443\mathrm{K}$ in presence of excess concentrated sulfuric acid it produces ethene as the product.
• The balanced chemical reaction can be represented as:

$\underset{\mathrm{Ethanol}}{{\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{OH}\left(\mathrm{aq}\right)}+\underset{\mathrm{Sulphuric}\mathrm{acid}}{{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{conc}\right)}\to \underset{\mathrm{Ethene}}{{\mathrm{CH}}_2={\mathrm{CH}}_2\left(\mathrm{l}\right)}+\underset{\mathrm{Water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{aq}\right)}$
