  • Breaking bonds - bond fission
  • Bonds can either break by Heterolytic fission or Homolytic fission

Heterolytic Fission

  • Both of the shared electrons go to just one atom when the bond breaks
  • Atom then becomes -ve charged
  • Has one more electron than proton
  • Other atom is +ve charged
  • Common in polar bonds

eg.

Homolytic Fission

  • One of the two shared elecrtons goes to each atom

  • They are highly reactive atoms with unpaired electrons - radicals

Radicals

  • Unpaired electron makes it extremely reactive
  • NO isnt such a
