2.11b: demonstrate an understanding of the concept of a reaction mechanism and that bond breaking can be homolytic or heterolytic and that the resulting species are either free radicals, electrophiles or nucleophiles

Reaction mechanisms are step-by-step descriptions of what occurs on a molecular level in chemical reactions.

  • homolytic: when the bonding electron pair is split evenly INSERT DIAGRAM HERE
    • often produces free radicals
  • heterolytic: when the bonding electron pair in unevenly split INSERT DIAGRAM HERE
