OR

How is carbon tetrachloride produced by substituting the hydrogen atoms of methane by chlorine atoms in steps?

WBBSE Class X Physical Science Organic Chemistry 03 Mark 2024

Answer

CH3CH2OH (Vapour) \overset {Al_2O_3,\ 350°C} {\longrightarrow} H2C = CH2 (Ethylene) + H2O

The two uses of Ethylene are:

  1. To ripen fruit and for fruit preservation.
  2. To make plastic polyethylene.

OR

Carbon tetrachloride (CClâ‚„) is produced by chlorinating methane (CH4) in several steps:

CH4 + Cl2 → CH3Cl + HCl

CH3Cl + Cl2 → CH2Cl2 + HCl

CH2Cl2 + Cl2 → CHCl3 + HCl

CHCl3 + Cl2 → CCl4 + HCl
