Bases

• Strong bases have a net negative charge, but not
  all negatively charged species are strong bases.
  For example, none of the halides F, Cl, Br,
  or I, is a strong base.
• Strong bases have weak conjugate acids.
• Carbanions, negatively charged carbon atoms, are
  especially strong bases. A common example is
  butyllithium.

Lewis Acids/Bases

• A Lewis acid is an electron pair acceptor.
• A Lewis base is an electron pair donor.
• Lewis bases are the same as BrØnsted-Lowry bases.
  Both have an available electron paira lone pair
  or a ? bond.
• Any species that is electron deficient and
  capable of accepting an electron pair is a Lewis
  acid.

Lewis Acid/Base Reactions

• In a Lewis acid-base reaction, a Lewis base
  donates an electron pair to a Lewis acid.
