Localized Bonding via Hybridization

• 1. Draw octet Lewis dot structure and
  determine SN of each central atom
• 2. Determine hybridization of central atoms
• SN 2 3 4 5 6
• sp sp2 sp3 dsp3 d2sp3
• 3. Combine hybrids and other atoms orbitals to
  make sigma bonds giving correct structure
• 4. Use left over p orbitals to make p bonds
• Use left over hybrids as non-bonding orbitals
• Next time more examples and delocalized bonding
