Question

Write the equation for the preparation of carbon tetrachloride from methane.

Answer 1

Preparation of carbon tetrachloride from methane

• In presence of sunlight, Chlorine (${\mathrm{Cl}}_2$) reacts with Methane (${\mathrm{CH}}_4$).
• where the Chlorine ($\mathrm{Cl}$) atoms replaces all four the hydrogen atoms consecutively to gives Carbon tetrachloride (${\mathrm{CCl}}_4$) as the product.
• The equations involved in the preparation of Carbon tetrachloride from Methane are as follows

$\underset{\mathrm{Methane}}{{\mathrm{CH}}_4\left(\mathrm{g}\right)}+\underset{\mathrm{Chlorine}}{{\mathrm{Cl}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Chloromethane}}{{\mathrm{CH}}_3\mathrm{Cl}\left(\mathrm{g}\right)}+\underset{\mathrm{Hydrogen}\mathrm{chloride}}{\mathrm{HCl}\left(\mathrm{g}\right)}$

$\underset{\mathrm{Chloromethane}}{{\mathrm{CH}}_3\mathrm{Cl}\left(\mathrm{g}\right)}+\underset{\mathrm{Chlorine}}{{\mathrm{Cl}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Dichloromethane}}{{\mathrm{CH}}_2{\mathrm{Cl}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Hydrogen}\mathrm{chloride}}{\mathrm{HCl}\left(\mathrm{g}\right)}$

$\underset{\mathrm{Dichloromethane}}{{\mathrm{CH}}_2{\mathrm{Cl}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Chlorine}}{{\mathrm{Cl}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Chloroform}}{{\mathrm{CHCl}}_3\left(\mathrm{g}\right)}+\underset{\mathrm{Hydrogen}\mathrm{chloride}}{\mathrm{HCl}\left(\mathrm{g}\right)}$

$\underset{\mathrm{Chloroform}}{{\mathrm{CHCl}}_3\left(\mathrm{g}\right)}+\underset{\mathrm{Chlorine}}{{\mathrm{Cl}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Carbon}\mathrm{tetrachloride}}{{\mathrm{CCl}}_4\left(\mathrm{g}\right)}+\underset{\mathrm{Hydrogen}\mathrm{chloride}}{\mathrm{HCl}\left(\mathrm{g}\right)}$
