Question: Explain the mechanism of chlorination of methane?
Chlorination of methane is the reaction between methane and chlorine to produce chloromethane and hydrogen chloride gas. This reaction follows a mechanism known as free-radical chlorination in which chlorine acts as a chlorinating agent. The process starts when methane and chlorine come together to form a reactive intermediate, a chlorine-containing free radical species called CH3•Cl. This intermediate is highly reactive and quickly reacts further to form chloromethane and a chlorine atom (Cl•). The chlorine atom then reacts with another molecule of methane to form another chlorine-containing intermediate, CH3Cl•, and so on and so forth until there are no more molecules of methane left. This process ends with a large number of chloromethanes, hydrogen chloride and other small molecules formed as side-products.
