Presentation Transcript

  1. Valence Bond & hybridization The orbital pattern valence electrons for 6C are: __ __ __ __ 2s 2px 2py 2pz The 4 bonds in CH4 are identical. The explanation is that valence electrons hybridize into an sp3 hybrid: __ __ __ __ sp3 See also Molecular Shape and Orbital Hybridization (google-youtube)

  2. Valence Bond & hybridization Google-youtube: Valence bond: molecular shape and orbital hybridization. See Text page 408.

  3. Valence Bond & hybridization The bond angle for H2O is 105o. H2S bond angle is closer to normal p orbitals (90o).

  4. Valence Bond & hybridization The orbital pattern valence electrons for 8O is: __ __ __ __ 2s 2px 2py 2p H2O The 2 bonds in H2O are identical. The explanation is that valence electrons bond angles change and hybridize into an sp3 hybrid: __ __ __ __ sp3

  5. Valence Bond & hybridization The orbital pattern valence electrons for each 6C in C2H4 (sp2 hybridization) is: __ __ __ __ sp2 (σ’s) p σ See also section 7 5 sigma and pi bonds (google-youtube)

  6. Valence Bond & hybridization Draw the line bond formula Shown right in your journal. Write the molecular geometry and orbital hybridization for the following atoms in the line bond formula. 1. N 2. O 3. C in CCO 4. C in NCC 5. C in HCH 5. Locate the sigma (σ) and pi (π) bonds. Write the following bond angles: 6. _____NCC 7. _____CCO 8. _____CCC 9. _____HCH
