Question

Write a balanced chemical for each of the following:

Heating of Ethanol at $170°C$ in the presence of conc. Sulphuric acid.

Answer 1

Balanced chemical for Heating of Ethanol at $170°C$ in the presence of conc. Sulphuric acid.

• When Ethanol$\left({\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}\right)$ is heated at $170°C$ in presence of concentrated Sulphuric acid $\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$, Ethene is is going to be formed as a product.
• This method is used to prepare Ethene from Ethyl alcohol.
• The chemical reaction is as follows.

$\underset{\mathrm{Ethanol}}{{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}\left(\mathrm{l}\right)}\stackrel{\mathrm{conc}.{\mathrm{H}}_2{\mathrm{SO}}_4}{\to }\underset{\mathrm{Ethene}}{{\mathrm{CH}}_2={\mathrm{CH}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$
