Presentation Transcript

  1. Day 3 Agenda • Discuss bond angles • Review hybridization • Work on determining orbitals involved in bonding • Write Results for qualitative analysis lab

  2. Effect Bond Angles p399 • Lone pairs • Require more space • Reduce bond angle • Double/triple bonds • Require more space, therefore reduce bond angle • Highly electronegative elements • Draw e- towards self, increasing bond angle

  3. MgCl2 • Number of bonds • Geometry • Bond angle • Dipole moment • hybridization

  4. SO2 • Number of bonds • Geometry • Bond angle • Dipole moment • hybridization

  5. H2S • Number of bonds • Geometry • Bond angle • Dipole moment • hybridization

  6. XeF2 • Number of bonds • Geometry • Bond angle • Dipole moment • hybridization

  7. BF3 • Number of bonds • Geometry • Bond angle • Dipole moment • hybridization

  8. NF3 • Number of bonds • Geometry • Bond angle • Dipole moment • hybridization

  9. ClF3 • Number of bonds • Geometry • Bond angle • Dipole moment • hybridization

  10. SF4 • Number of bonds • Geometry • Bond angle • Dipole moment • hybridization

  11. CF4 • Number of bonds • Geometry • Bond angle • Dipole moment • hybridization

  12. XeF4 • Number of bonds • Geometry • Bond angle • Dipole moment • hybridization

  13. PF5 • Number of bonds • Geometry • Bond angle • Dipole moment • hybridization

  14. IF5 • Number of bonds • Geometry • Bond angle • Dipole moment • hybridization

  15. SF6 • Number of bonds • Geometry • Bond angle • Dipole moment • Hybridization

  16. Orbital Shapes • “Flower” • Spherical • Dumb bell • Parabolic

  17. Valence Bond Theory • Explains the covalent bond by quantum mechanics • Orbitals overlap – gives strength to bond • No more than 2 electrons in both orbits • Hybridization • Energy level between s and p

  18. Orbitals

  19. Qualitative Analysis Lab Report • You’re on your own this time! • Intro – quality – (qualitative) • FLOW • M & M – in your own words • Past tense of what you did with mishaps • Results – may be the same between partners • Preferable • Conclusions – on your own
