  3. Hybrid orbitals are orbitals of equal energy produced by the combination of two or more orbitals on the same atom.

  4. VSEPR theory is useful for explaining the shapes of molecules.

  5. Hybridization Notes

    -to explain how the orbitals of an atom are rearranged when the atom forms covalent bonds, hybridization is used.
    - Hybridization = the mixing of 2 or more atomic orbitals of similar energies on the same atom to produce new hybrid atomic orbitals of equal energies

    e.g. CH4 (Methane)

    - C has 4 valence electrons (2 in 2s and 2 in 2p)
    - it is tetrahedral
    -to achieve 4 equivalent bonds, carbon's one 2s and three 2p orbitals hybridize to form 4 new, identical orbitals called sp^3

    - all 4 (s,p,p,p) hybrid orbitals in the sp&3 are equivalent in energy.
    - 2s < hybrid energy < 2p

  8. Hybridization

    VSEPR Theory is useful for predicting and explaining the shapes of molecule.

    A step further must be taken to explain how the orbitals of an atom are rearranged when the atom forms covalent bonds.

    For this purpose, we use the model of hybridization, which is the mixing of two or more atomic orbitals of similar energies.

    This site pretty much covers everthing we have talked about this chapter
