Classifications and reactions involving carbon radicals

 
Classification of radical reactions
  • Radical are generally very reactive species with a short lifetime. If the reaction rate can be controlled, selectivity of radical reactions can be improved. Radicals can undergo,
    1. Substitution
    2. Addition
    3. Rearrangement
    4. Auto-oxidation
    5. Single electron transfer (SET).
 
Substitution Reactions:

This radical reaction involves substitution of smaller molecules, (e.g., chlorination of methane). The reaction function as a chain substitution reaction.

  • This radical reaction involve substitution of smaller molecules,the well known evident reaction is chlorination of methane. The reaction function as a chain substitution.
