1. Drill: Draw & name 3 isomers of C 5 H 12

2. Alkenes

3. Hydrocarbons with at least one double bond

4. Alkenes Each double bond reduces the number of hydrogens in the hydrocarbon by two

5. Alkenes All alkenes are unsaturated hydrocarbons

6. Unsaturated Hydrocarbons Contain less than the maximum number of hydrogens

7. Alkenes

8. Naming Alkenes Number the carbons on the chain; so that, the double bond has the lowest possible number

9. Naming Alkenes The double bond will always fall between two numbered carbons

10. Naming Alkenes Apply the lower of those two numbers to the double bond

11. Naming Alkenes 1 2 3 4 2-butene

12. Problems 1 2 3 4 1 23 4

13. Geometric Isom. 1 2 3 4 1 23 4

14. Geometric Isomers Isomers whose arrangement is same side (cis) or opposite side (trans) of a stationary bond

15. Naming Alkenes Draw a line through the double bond parallel to each of the bonds in the double bond

16. Naming Alkenes 1 2 3 4

17. If the two ends of the chain are on the same side of the line, it is a cis-double bond

18. Naming Alkenes If the two ends of the chain are on opposite sides of the line, it is a trans-double bond

19. Naming Alkenes Place cis or trans at the start of the name in the organic compound

20. Naming Alkenes 1 2 3 4 trans-2-butene

21. Draw the Following: trans-3-ethyl-4,6-dimethyl- 5-cyclopentyl-2-octene

22. Drill: Draw the condensed, skeletal, & stick structures for: cis-3-ethyl-4,6-dimethyl-5- cyclopropyl-2-octene

23. Organic Chm HW Test 2 on Cycloalkanes & alkenes is on Friday
