Student Learning Outcomes:
Upon completion of this lesson, you will be able to:

Distinguish the difference between homolytic and heterolytic cleavage.

Describe the three phases (initiation, propagation, and termination) of radical chain reaction with radical initiators involved in homolytic cleavage.

Apply homolytic bond dissociation energies to describe the energy level diagram and the propagation process.

Compare the energy changes for halogenation (substitution) between halogens.

Approximate time required for the readings for this lesson (at 144 words/minute): 45 minutes.
