What role do radicals play in a radical propagation reaction?

Question

Quizplus · Accepted Answer

Radicals are both reactants and products in a radical propagation reaction. In the initial step of the reaction, a radical initiates the reaction by cleaving a covalent bond to form two new radicals. These new radicals then react with the original reactants to create even more radicals, leading to the propagation of the reaction. As the reaction proceeds, some radicals will react with each other to form stable products, while others will continue the propagation by reacting with additional reactants to generate even more radicals. Therefore, radicals play a vital role in the propagation of a radical reaction.
