Explain the mechanism of chlorination of methane, according to Free Ra

1.	Explain the mechanism of chlorination of methane, according to Free Radical.
Answer» Mechanism of chlorination of methane involves three types. Step 1. Initiation: Chlorine absorbs energy and undergoes homolysis to give chlorine free radicals. Cl - Cl \(\overset{hy}{\longrightarrow}\) 2Cl^• Step 2 : Propagation: Chlorine free radical reacts with methane to give methyl free radical. Cl^• + CH₄ → CH₃^• + HCl The methyl free radical reacts with chlorine to form methyl chloride and chlorine free radical. CH₃^• + Cl₂ → CH₃Cl + Cl^• Step 3 : Termination: Free radials combine to form stable products. Cl^• + Cl^• → Cl₂(Chlorine) CH₃^• + CH₃^• → C₂H₆(Ethane) CH₃^• + Cl^• → CH₃Cl (Methyl Chloride)

Explain the mechanism of chlorination of methane, according to Free Radical.

Answer»

Mechanism of chlorination of methane involves three types.

Step 1. Initiation: Chlorine absorbs energy and undergoes homolysis to give chlorine free radicals.

Cl - Cl \(\overset{hy}{\longrightarrow}\) 2Cl^•

Step 2 : Propagation: Chlorine free radical reacts with methane to give methyl free radical.

Cl^• + CH₄ → CH₃^• + HCl

The methyl free radical reacts with chlorine to form methyl chloride and chlorine free radical.

CH₃^• + Cl₂ → CH₃Cl + Cl^•

Step 3 : Termination: Free radials combine to form stable products.

Cl^• + Cl^• → Cl₂(Chlorine)

CH₃^• + CH₃^• → C₂H₆(Ethane)

CH₃^• + Cl^• → CH₃Cl (Methyl Chloride)
