Presentation Transcript

  1. The reactivity of organic compoundsBond enthalpies KJmol-1C-O bond weakest (336 KJmol-1) and easiest to break in ethanol. However the O-H bond also breaks in other reactions (464 KJmol-1)!

  2. Bond Energies/KJ mol-1

  3. Polarity When two different atoms are covalently bonded, the atoms in the bond will always be more electronegative than the other. Electronegativity

  4. Electronegativities and bond energies in carbon-halogen bonds • As we go down the group from fluorine to iodine: • The carbon-halogen bonds get weaker (easier to break) • The bonds get less polar and therefore the carbon becomes less easily attacked by negatively charged species (nucleophile)
