  1. Organic Chemistry Applied Chemistry Milbank High School

  2. Organic Chemistry • Chemistry of compounds that contain carbon • Combine mainly with hydrogen, oxygen, and nitrogen • Over 10 million compounds made with these 4 elements • 95% of compounds contain carbon

  3. Properties • Very Flammable! • Combustion reactions • Don’t react with other compounds much

  4. Types • Hydrocarbons • Alcohols, phenols, ethers • Carboxylic acids, amines, ketones

  5. Hydrocarbons • Methane, ethane, propane • Ethylene • Acetylene

  6. Alcohols • Methanol • Ethanol • Isopropyl alcohol

  7. Ethanol • Wines • 12% ethanol • Champagnes • 14-20% ethanol • Beers • 4% ethanol • Whiskey • 50% ethanol Proof spirit: alcoholic content of a beverage, twice that of the alcohol content by volume (whiskey: 100 proof)

  8. Ethanol Con’t • Toxic to humans • Acute poisoning kills several hundred a year (drinking contests) • Long term poisoning • Most serious drug problem in US • 40 times more addicts than heroin

  9. More alcohols • Nitroglycerin • Ethylene glycol • Identification of alcohols: • Contain an OH group

  10. Alcohol in the Blood • Ethanol is a depressant, not a stimulant • Diminished judgment and less control of actions • Does NOT keep you warm in cold weather • Causes blood vessels to dilate • Accelerates the loss of heat loss • ½ of all frostbite victims are legally drunk • Shortens life span by contributing to diseases of the liver, cardiovascular system, and almost every other organ in the body

  11. Octane Rating • Amount of octane (isooctane) present in gasoline • Remainder is heptane • Catalytic reforming • Change low octane fuels into high octane fuels • Additives • Ethers, alcohols

  12. Distillation • Method of separating chemicals based upon their boiling point • Crude oil • Water from salt water etc • Alcohol

  13. Titration • Used to determine the concentration of a known reactant • Indicator • Shows when the solutions are at equilibrium • Utilizes precise measurements and requires accurate lab skills
