What happens when methane reacts with chlorine? Give equation of the reaction which takes place.
When methane reacts with chlorine, substitution reaction takes place. Methane reacts with chlorine in the presence of sunlight to form chloromethane and hydrogen chloride. In this reaction, chlorine substitutes hydrogen; therefore, this reaction is also known as chlorination.
The chemical equation for this reaction is
`CH_4 + Cl_2 -> CH_3 Cl + HCl`
