chemical bonds

  1. 1. Chemical bonds Presented by: Julian Arboleda Chemical bonds
  2. 2. Covalent Bonds <ul><li>Covalent bonding is a common type of bonding, in which the electronegativity difference between the bonded atoms is small or non-existent. Bonds within most organic compounds are described as covalent. See sigma bonds and pi bonds for LCAO-description of such bonding. </li></ul>
  3. 3. Ionic Bonds <ul><li>Ionic bonding is a type of electrostatic interaction between atoms which have a large electronegativity difference. There is no precise value that distinguishes ionic from covalent bonding but a difference of electronegativity of over 2.0 is likely to be ionic and a difference of less than 1.5 is likely to be covalent.[4] Ionic bonding leads to separate positive and negative ions. Ionic charges are commonly between −3e to +3e. </li></ul>
  4. 4. Polar Covalent <ul><li>Polar covalent bonding is intermediate in character between a covalent and an ionic bond. It attracs the atoms because their charges, it share the electrons of valence </li></ul>
  5. 5. Hydrogen Bond <ul><li>In some ways this is an especially strong example of a permanent dipole, as above. However, in the hydrogen bond, the hydrogen proton comes closer to being shared between target and donor atoms, in a three-center two-electron bond like that in diborane. Hydrogen bonds explain the relatively high boiling points of liquids like water, ammonia, and hydrogen fluoride, compared with their heavier counterparts in the same periodic table column. </li></ul>
