Differences between free radical and ionic reactions

Free radical reactions

  • The reactions proceed through free radicals produced by hemolytic fission of covalent bonds.
  • They are catalyzed by light, peroxide and high temperature.
  • These reactions occur in non-polar solvents or in gaseous state.
  • They are usually chain reaction.
  • They are hindered by free radicals.

Polar or ionic reactions

  • The reactions proceed through ions produced by heterolytic fission of covalent bonds.
  • These reactions are catalyzed by acid or base.
  • They occur in polar solvents.
  • They are not chain reaction.
  • They are not influenced by free radicals.
