1. WARM UP 1.Write your own brief definition of the word “organic.” 2.What makes something organic?

2. The Big Bang Theory

3. Organic Base Chains Chemistry II

4. Organic Chemistry Study of organic molecules – Carbon compounds Focus on structural formulas

5. Organic Chemistry Deals mostly with hydrocarbons – Made of carbon and hydrogen – Useful in: Fuels Living cell structures (retina)

6. Base Chains A string of carbon and hydrogen – Aliphatic Straight chain (open or closed) – Aromatic Ring

7. Aliphatic Chains Alkanes – C n H 2n +2 – Single bonds – Saturated Full of hydrogen

8. Aliphatic Chains Alkanes con’t.. – Isomers Same atoms, different shape n- (straight) and iso- (T-shape) Cycloalkanes – End of chain connected in a ring

9. Aliphatic Chains Alkenes – C n H 2n – 1 or more C=C double bond – Unsaturated Could hold more H

10. Aliphatic Chains Alkenes con’t… – Isomers Position of double bond cis- or trans- – Sides chains off double bond are on – cis- = U-shape trans- = chair shape

11. Aliphatic Chains Alkynes – C n H 2n-2 – 1 or more C ≡ C triple bond

12. Aromatic Chains Made of benzene (6 C) rings – Alternating single and double bonds – Many rings can stick to each other

13. WRAP UP Draw… – An n-alkane – An iso-alkane – A cycloalkane – An alkene – An alkyne – An aromatic
