Redox Reactions

• A reduction is a reaction that results in a gain of

  electron density for carbon.
• An oxidation is a reaction that results in a loss of

  electron density for carbon.
• Catalytic hydrogenation is a process by which hydrogen is

  added, in the presence of a metal catalyst, to the unsaturated

  hydrocarbons (alkene or alkyne) in compounds to form

  saturated hydrocarbons (alkane).
• Reduction reaction leads to increase of C-H bonds.
• Oxidation reaction leads to increase of C-Z bonds
