Clear A-level chemistry explanation of free radical substitution using methane and chlorine. In organic chemistry, a radical-substitution reaction is a substitution reaction involving free radicals as a reactive intermediate. [1] The reaction always involves at least two steps, and possibly a third. Instead of electrophilic aromatic substitution, the benzene ring undergoes substitution of hydrogen atoms by chlorine atoms on the side chain or on the ring itself, depending on conditions.
