WebJul 25, 2024 · Photochlorination - The Reaction between Methane and Chlorine WebSummary. Alkanes are saturated hydrocarbons. Methane is a simple example of alkanes. They show low chemical reactivity due to saturation compared to alkenes or alkynes. The halogenation of alkanes forms haloalkanes via free radical reaction mechanism. Halogenation reaction involves three steps, initiation, propagation & termination.
