WebApr 6, 2024 · In Chemistry, a free radical is an atom or a molecule free in its space and independent in its nature. The molecules that have unpaired electrons are called free radicals, and such radicals can be easily mixed with their respective components without getting affected by the outside atmosphere. WebThe 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.
