  1. Drill:Find the age of a tooth that contains 1.8 % of its original C-14t1/2 C-14 = 5730 yrs

  2. Distribute Tests

  3. Review Test & Drill

  4. Organic Chemistry

  5. Organic HW • Review PP-30 & PP-31 • Complete the attached assignment & turn it in tomorrow

  6. Organic HW Draw the Lewis Dot Diagrams For: C4H10 C4H8 C4H6 C4H4

  7. Begin Instruction

  8. Organic Chemistry • The chemistry of carbon compounds • Sometimes called carbon chemistry

  9. Organic Chemistry • The backbone element in the molecules of all living things is carbon

  10. Carbon Chemistry • Carbon is one of the only elements that can form long chains • Carbon can form 4 covalent bonds

  11. Organic Chemistry • Carbon forms covalent bonds with hydrogen, oxygen, nitrogen, phosphorus, sulfur, and the halogens

  12. Carbon Bonding • Carbon has 4 valence electrons which can hybridize in many ways

  13. Carbon Bonding • To determine the hybridization, draw the Lewis Dot Diagram of the carbon compound

  14. Hybridization • sp3 4-single bonds • sp2 2-single bonds & • 1-double bond • sp 2 doubles or T + S

  15. Multiple Bonds • To make multiple bonds, p-orbitals are required

  16. Hybridization • sp3 no p-orbitals • sp2 1 p-orbital • sp 2 p-orbitals

  17. Single bonds & the first bond in multiple bonds involve end-to-end overlap: s

  18. Multiple Bonds • After the 1st bond, any others are p p bonds: side-to-side p-overlap

  19. AX4 or sp3 H H-C-H H

  20. AX3 or sp2 H C=O H

  21. AX2 or sp O=C=O H-C N

  22. Carbon Bonds • sp3 4 s bonds • sp2 3 s & 1 p bonds • sp 2 s & 2 p bonds • sp 2 s & 2 p bonds

  23. Carbon sp3 Shapes • AX4 tetrahedral • AX3E trigonal • pyramidal • AX2E2 v-shaped

  24. AX4 or sp3 H H-C-H H

  25. AX3E or sp3 .. R-N-H H

  26. AX2E2 or sp3 .. R-O: H

  27. Carbon sp2 Shapes • AX3 trigonal • planar • AX2E v-shaped

  28. AX3 or sp2 H C=O H

  29. AX2E or sp2 O S: R

  30. Carbon sp Shape • AX2 linear

  31. AX2 or sp O=C=O H-C N

  32. Draw Lewis Dot Diagrams for each of the following with proper angles: C3H8 C3H6 C3H4
