Transcript

  • 1. Intermolecular forces13-Nov-12 1
  • 2. Overview intramolecular bonds attraction in molecules intermolecular forces13-Nov-12 2
  • 3. Intermolecular forces is much weaker than intramolecular forces13-Nov-12 KARBOHIDRAT 3
  • 4. INTERMOLECULAR FORCES ---- attraction that exist between molecule 1. GAYA VAN DER WAALS • GAYA DIPOLE-DIPOLE • GAYA LONDON (DISPERSI) 2. IKATAN HIDROGEN13-Nov-12 4
  • 5. 1. Gaya dipole-dipole....dipole-dipole force2. Gaya london (dispersi)....dispersion force4. Ikatan hidrogen......hydrogen bonding5. Ikatan ionik....ionic bonding6. Jaringan ikatan kovalen.....covalent network13-Nov-12 5
  • 6. What should be discussed : 1. What ? 2. When? 3. Example? 4. Power?13-Nov-12 6
  • 7. London dispersion force •The attraction between atoms and molecules caused by the formation of instantaneous atoms in the atoms and molecules •Two non polar molecule •Caused by momentary dipole13-Nov-12 7
  • 8. 13-Nov-12 KARBOHIDRAT 8
  • 9. 13-Nov-12 KARBOHIDRAT 9
  • 10. polarizability• the ease with which an atom or molecule can be distorted to have an instantaneous dipole.13-Nov-12 KARBOHIDRAT 10
  • 11. Polarizability increases with: greater number of electrons Dispersion forces usually increase with molar mass.13-Nov-12 KARBOHIDRAT 11
  • 12. Effects on boiling points13-Nov-12 12
  • 13. Dipole-dipole force• The force that exist between negative and positive ends of a polar molecule.• Between two polar molecule + - + - Opposite attraction13-Nov-12 13
  • 14. 13-Nov-12 KARBOHIDRAT 14
  • 15. Hydrogen bonding• A form of dipole attraction in which hydrogen atom bonded to a strongly electronegative atom• H + F, O, N .... HF, NH3, H2O• Works like dipole-dipole but 5 times stronger13-Nov-12 KARBOHIDRAT 15
  • 16. Ionic bonding• The forces holding ions together in ionic solids are electrostatic forces13-Nov-12 KARBOHIDRAT 16
  • 17. •100 % covalent bond •There are no intermolecular force •Only compounds of C only (diamond, graphite) and Si (usually with Oxygen) • very strong attraction13-Nov-12 KARBOHIDRAT 17
  • 18. 13-Nov-12 KARBOHIDRAT 18
  • 19. 13-Nov-12 KARBOHIDRAT 19
  • 20. power Jaringan ikatan kovalen > Ikatan ionik > Ikatan hidrogen > dipol-dipol > gaya london13-Nov-12 20
