"A person goes to knowledge as he goes to war, wide-awake, with fear, with respect and with absolute assurance...If such a person fails, or suffers a defeat, he will have lost only a battle, and there will be no pitiful regrets over that"

Don Juan

Objectives:

  1. Know that alcohols are oxidized to aldehydes and ketones (and how this explains how a breathalyzer works).
  2. Know the structures and toxicity of the antifreezes ethylene glycol and propylene glycol.
  3. Know why ethanol is administered intravenously as a treatment for methanol and ethylene glycol poisoning.
  4. Know structures for glycerol and that

    5. glycerol + fatty acids ® triglyceride (fats and oils)

    (note: glycerol is an alcohol, fatty acids are carboxylic acids and triglycerides are esters)

  5. Recognize ethers and know that ethers are nonpolar.
  6. Be able to draw structural formulas for aldehydes and ketones.
  7. Know what products are produced from oxidation and reduction of aldehydes and ketones.
