Intermolecular chemical bonding

  1. 1. INTERMOLECULARCHEMICAL BONDING
  2. 2. Covalent Disulfide Bond Ion-Dipole Force of attraction between INTERMOLECULAR molecules.CHEMICAL BONDING Polar Dipole-Dipole H-Bonding Non-Covalent Vander Waals Non-Polar Pi-Pi Complex Hydrophobic
  3. 3. Covalent:Disulfide Bond
  4. 4. Covalent: Disulfide BondAttraction between cysteine residue.Linkage is also called an SS-bond or disulfide bridge.Overall connectivity is therefore R-S-S-R.
  5. 5. Covalent: Disulfide BondFormal Depiction of Disulfide Bond Formation as an Oxidation.
  6. 6. Covalent: Disulfide BondCystine, which is Composed of TwoCysteines Linked by a Disulfide Bond.
  7. 7. Non-Covalent:Polar:Ion-Dipole
  8. 8. Non-Covalent: Polar: Ion-Dipole Attraction between ionic compound and dipole molecule.Cations are attracted to the negative end of a dipole .Anions are attracted to the positive end of a dipole.Ex. a salt in aqueous solvent
  9. 9. Non-Covalent: Polar: Ion-DipoleAn Ion-Dipole Force Exist Between a Charged Ion and a Polar Molecule.
  10. 10. Non-Covalent:Polar:Dipole-Dipole
  11. 11. Non-Covalent: Polar: Dipole-Dipole Attraction between opposite charges of polar molecule. Polar molecules attract one another when the partial positive charge on one molecule is near the partial negative charge on the other molecule The polar molecules must be in close proximity for the dipole-dipole forces to be significant. Dipole-dipole forces are weaker than ion-dipole forces.
  12. 12. Non-Covalent: Polar: Dipole-DipoleA Dipole-dipole Force Exists Between Neutral Polar Molecules.
  13. 13. Non-Covalent: Polar: Dipole-DipoleHCL, With a Dipole-Dipole Force
  14. 14. Non-Covalent:Polar:Hydrogen Bond
  15. 15. Non-Covalent: Polar: Hydrogen BondForce of attraction between H and more electronegative atom of another molecule: √ Hydrogen – 2.1 √ Nitrogen – 3.0 √ Oxygen – 3.5 √ Fluorine – 4.0 considered to be dipole-dipole type interactions, but are stronger than dipole- dipole forces.
  16. 16. Non-Covalent: Polar: Hydrogen Bond The hydrogen atom has no inner core of electrons, so the side of the atom facing away from the bond represents a virtually naked nucleus. This positive charge is attracted to the negative charge of an electronegative atom in a nearby molecule. Because the hydrogen atom in a polar bond is electron- deficient on one side, this side of the hydrogen atom can get quite close to a neighboring electronegative atom.
  17. 17. Non-Covalent: Polar: Hydrogen BondWater, Forming an Extensive Hydrogen Bonding Network
  18. 18. Non-Covalent:Non-Polar:Vander Waals
  19. 19. Non-Covalent: Non-Polar: Vander Waals Attraction between the proton and valence electron of another non-polar molecule. Strength of VDW: SOLID>LIQUID>GAS
  20. 20. Non-Covalent:Non-Polar:Pi-Pi Complex
  21. 21. Non-Covalent: Non-Polar: Pi-Pi Complex Interaction between aromatic molecules. Also called pi-pi interaction or plot stocking. Ex. Attraction between benzene and phenol.
  22. 22. Non-Covalent:Non-Polar:Hydrophobic
  23. 23. Non-Covalent: Non-Polar: HydrophobicHYDROPHOBIC MOLECULES  Are repelled by water (literally, hydrophobe means fear of water).  Includes alkanes, oils, fats, and other greasy substances.  Tend to be electrically neutral and non-polar and work better with neutral and non-polar solvents.  Often cluster together when dropped in water.
  24. 24. Non-Covalent: Non-Polar: Hydrophobic Interaction between Hydrocarbons or other non- polar molecules. In a hydrophobic interaction, water is rejecting the hydrophobic molecules in favor of bonding to itself (intermolecular H-bond). Water bonds easily with polar molecules (likes dissolve likes).  Since water itself is polar, it will prefer water molecules (polar) rather than oil molecules (non-polar).
  25. 25. Non-Covalent: Non-Polar: HydrophobicHydrophobic molecules cluster together though theyre not attracted to each other, because large numbers of like molecules are energetically more favorable than smaller numbers (thermodynamics).
