Introduction to Free Radical Substitution Reactions
2011年10月25日 · Free-radical reactions require a radical “initiator” that breaks bonds homolytically. This can be either “light” (hv) or “heat” in the presence of various radical “initiators” with weak bonds, such as “peroxides” (RO-OR) or other species like AIBN.
What is Free Radical Substitution? - Chemistry LibreTexts
2023年1月23日 · Free radicals are atoms or groups of atoms which have a single unpaired electron. A free radical substitution reaction is one involving these radicals. Free radicals are formed if a bond splits evenly - each atom getting one of the two electrons. The name given to this is homolytic fission.

6.3: Radical Reactions - Chemistry LibreTexts
A radical substitution reaction is a reaction which occurs by a free radical mechanism and results in the substitution of one or more of the atoms or groups present in the substrate by different atoms or groups.

2022年10月11日 · The free-radical substitution reaction consists of three steps: In the initiation step, the halogen bond (Cl-Cl or Br-Br) is broken by UV energy to form two radicals; These radicals create further radicals in a chain reaction called the propagation step; The reaction is terminated when two radicals collide with each other in a termination step
Free Radical Substitution | CIE AS Chemistry Revision Notes 2025
2023年11月21日 · The free-radical substitution reaction consists of three steps: Initiation step. In the initiation step, the Cl-Cl or Br-Br is broken by energy from the UV light; This produces two radicals in a homolytic fission reaction; Free radical initiation
These reactions include free radical halogenations of alkanes and free radical additions to alkenes. Some aspects of these reactions cause them to be more complex than ionic reactions.

2023年1月23日 · This page gives you the facts and a simple, uncluttered mechanism for the free radical substitution reaction between methylbenzene (previously known as toluene) and chlorine. What is Free Radical Substitution?
Free Radical Reactions – Master Organic Chemistry
2013年7月30日 · In this post we introduce the concepts of homolytic bond breakage, single-barbed curved arrows, free radicals, and free-radical substitution through the example of chlorination of alkanes with Cl 2 and light, which will lay the foundation for this series on free-radical chemistry.
