Give the names of the different stages of the chlorination of methane.

(N/A) The chlorination of methane proceeds through a free radical mechanism consisting of three main stages:
$I$. Initiation: The homolytic cleavage of $Cl_2$ to form chlorine radicals $(Cl^{\bullet})$.
$II$. Propagation: The chain reaction where radicals react with molecules to form new radicals and products.
$III$. Termination: The combination of two radicals to form a stable molecule.
