  1. CE 3231 - Introduction to Environmental Engineering and Science Readings for Next Class: Ohio Northern University Chemistry, Microbiology & Material Balance Introduction Water & Air Pollution Env Risk Management Organic Chemistry What’s in a name. And so it is with organic chemistry. The compounds that form with carbon are responsible for life itself. Therefore, understanding the amazing compounds that form from carbon and being able to name some of them is a step towards understanding environmental engineering.

  2. Lecture 7Organic Chemistry(Chemistry IV)

  3. Common Reaction Types Review

  4. Let’s play…Is it Organic or Inorganic Chemistry • happens in the environment • forms compounds with carbon • is important to life on earth • occurs in the ground • can go from one to the other • based upon 8 electrons • forms complexes with water

  5. Let’s play….Is it natural or synthetic • vinegar • teflon • fragrance • advil • botulism toxin • polypropylene • olefin

  6. Writing Molecules… • Structural • Linear • Condensed • Kinky

  7. Alkanes and Alkenes • Straight or branched chains of carbon • Meth – 1 • Eth – 2 • Prop – 3 • But – 4 • Pent – 5 • Hex – 6 alkanes have single bonds between carbons, alkenes have more… • Hept– 7 • Oct – 8 • Non – 9 • Dec – 10 • Undec– 11 • Dodec– 12

  8. Common Functional Groups

  9. Ringed Alkanes vs Aromatics • Aromaticity is the sharing of electrons around a ringed structure

  10. Form follows function…. ESTROGEN (Hormone) ALKYLPHENOL (detergent)

  11. Benzene and It’s Derivatives 6 2 4 3 1 5 1. 2. 3. 4. 5. 6.

  12. Polymers

  13. Polyaromatic Hydrocarbons (PAH)

  14. Oh…grasshoppa Semi volatile organic compounds can undergo long-range atmospheric transport

  15. The Dirty Dozen – Stockholm ConventionPersistent Organic Pollutants

  16. The Dirty Dozen – Stockholm ConventionPersistent Organic Pollutants

  17. Fate, Transport, & Effect

  18. Fate, Transport, & Effect
