Radical Chain Mechanism
The reaction proceeds through the radical chain mechanism. The radical chain mechanism is characterized by three steps: initiation, propagation and termination.  Initiation requires an input of energy but after that the reaction is self-sustaining.  The first propagation step uses up one of the products from initiation, and the second propagation step makes another one, thus the cycle can continue until indefinitely.

Understanding Halogenation
Halogenation is a chemical reaction where halogens (such as fluorine, chlorine, bromine, or iodine) are added to organic compounds, particularly alkanes and alkenes.
Free Radical Chain Mechanism
The correct answer to how halogenation proceeds is through the free radical chain mechanism. This process can be broken down into three main stages:
  • Initiation: This stage involves the formation of free radicals. For example, when chlorine gas (Cl2) is exposed to heat or light, it dissociates into two chlorine radicals (Cl•). These radicals are highly reactive.
  • Propagation: In this stage, the chlorine radicals react with the alkane molecules. A radical abstracts a hydrogen atom from the alkane, forming hydrochloric acid (HCl) and a new alkyl radical. This new radical can further react with another chlorine molecule, generating more chlorine radicals and continuing the chain reaction.
  • Termination: This final stage occurs when two radicals combine to form a stable product, effectively stopping the chain reaction. Termination can happen in various ways, such as the combination of two chlorine radicals or the combination of an alkyl radical and a chlorine radical.

Characteristics of Free Radical Mechanism
  • Chain Reaction: The process is characterized by a series of reactions that can propagate rapidly.
  • Temperature and Light Sensitivity: The initiation phase often requires heat or light, making it sensitive to environmental conditions.
  • Radical Stability: The stability of radicals influences the reaction pathway, affecting which products are formed.

In summary, halogenation primarily occurs through the free radical chain mechanism, involving initiation, propagation, and termination stages.
